Description
Technical Field
The invention belongs to the technical field of materials and environment, and particularly relates to a material for removing barium element in bittern and a preparation method thereof.
Background
Selenium is an essential trace element that can be metabolized by the human body. Thus, selenium materials are environmentally friendly. Selenium science has evolved rapidly over the last decade.
The main components in the brine are sodium chloride and sodium sulfate, and can be used for extracting industrial salt and anhydrous sodium sulfate. The extracted waste water contains elements such as calcium and magnesium, and if the extracted waste water is directly discharged, the environment pollution can be caused. These elements can be generally extracted to be used as products such as denitration agent, gypsum and the like, and the added value of these products is too low. If the method is applied to the preparation of medical consumables, the additional value of the medical consumables can be obviously improved, and the cost of wastewater treatment is compensated. However, since the brine contains a certain amount of barium element, the brine has higher toxicity, and medical consumables are directly manufactured by taking the brine as a raw material, the quality of the medical consumables can be greatly influenced, and the barium removal treatment is necessary. The development of the brine barium-removing material which is safe to the environment and biocompatible at the same time has good application value.
In general, barium is removed from brine in the prior art by chemical precipitation, sodium sulfate may be added to react with barium ions to form insoluble barium sulfate, so that barium ions are removed, but calcium and magnesium ions are removed simultaneously with the removal of barium.
In the Chinese patent database, a preparation method of a carbon-based selenium material and application thereof in dehalogenation of dimethyl carbonate are disclosed, and publication number CN113908861A; publication (bulletin) day: 20220111; the method comprises the steps of mixing and grinding glucose methylselenate and potassium bromide, calcining in a tube furnace for 2-4 hours at 450-550 ℃ under nitrogen atmosphere, cooling to obtain a solid, grinding the solid, washing the solid with deionized water in ultrasonic waves, and drying to obtain the carbon-based selenium material. The selenium source and the carbon source prepared by using the selenized glucose as the material are used for end capping, so that the stability of the raw materials can be improved, and the method is beneficial to industrial application. Methyl capping is a method for ensuring the catalytic activity of selenium species to the greatest extent, and can avoid deactivation of selenium atoms due to too deep landfill. This method does not teach how to remove barium from brine.
Disclosure of Invention
The invention aims to provide a carbon-based selenium material for removing barium from brine and a preparation method thereof, and the obtained carbon-based selenium material can be used for removing barium from brine, and has good environmental safety and biocompatibility.
For this purpose, the invention provides the following technical scheme: a carbon-based selenium material for barium removal of brine is prepared by mixing selenoglucose, ammonium carbonate and calcium carbonate according to a mass ratio of 1: (1-5): (80-120) and calcining for 1-3 hours at 400-600 ℃; and cooling to obtain the light gray powdery material which is the target product.
Preferably, the mixing weight ratio of the selenoglucose to the ammonium carbonate is 1:3:100. the results of a large number of comparison experiments prove that: the material prepared according to the proportion has the best performance. Selenium with high price can be fully utilized.
The preparation method comprises the following steps:
(1) Selenium glucose, ammonium carbonate and calcium carbonate are mixed according to the mass ratio of 1: (1-5): (80-120) mixing uniformly;
(2) Calcining the uniformly mixed material at 400-600 ℃ for 1-3 hours;
(3) And cooling to room temperature to obtain a light gray powdery material, namely the carbon-based selenium material of which the target product is used for barium removal of brine.
Preferably, the calcination temperature is 500 ℃ and the calcination time is 2 hours. The temperature and the calcination time just can decompose selenoglycose to make the selenoglycose become free selenium with higher activity, and the selenium volatilization loss caused by overhigh temperature and overlong calcination time is avoided, so that the prepared material has the best effect.
Compared with the prior art, the invention has the beneficial effects that: the obtained carbon-based selenium material has a certain adsorption capacity to barium ions in brine, and can obviously reduce the barium content in the brine. The invention uses selenoglucose as selenium source. After calcination, selenium in the material can have certain coordination capacity on barium and can be matched with heavy metal elements, so that barium in bittern can be removed. The calcium and magnesium in the brine belong to light elements and have weak coordination ability with selenium. Therefore, the carbon-based selenium material can selectively adsorb barium ions without affecting calcium and magnesium ions in the material, thereby realizing the selective barium removal of calcium and magnesium resources.
The selenoglucose as a carbon-based selenium material has biocompatibility and can be even directly used as a feed additive to improve the health condition of animals, so that the selenoglucose is safe to the environment. The ammonium carbonate can be decomposed during calcination, so that the material is more loose, has larger porosity, is favorable for absorbing heavy metals, and can be high in pore-forming efficiency by adopting ammonium carbonate with specific proportioning dosage, meanwhile, the calcium carbonate serving as a framework material is guaranteed to have better supporting effect, selenium generated after decomposition of selenoglycose can be uniformly loaded, and the framework material has good chemical stability and physical structural stability and can be used for better removing barium ions in bittern. The functional material provided by the invention can be used for independently removing barium ions in brine, has high selenium utilization efficiency, and can be used for manufacturing brine into medical grade consumables.
Detailed Description
Example 1:
1. And (3) preparing materials:
Selenoglucose is a known substance and can be prepared according to the methods reported in the literature (Ind. Eng. Chem. Res. 2020, 59, 10763-10767). We prepared selenoglucose according to the procedure described in this document, with selenium content of 0.63%, similar to the 0.59% reported in the document.
Subsequently, 10 g of the selenoglucose prepared above, 30 g of ammonium carbonate (analytically pure) and 1000 g of calcium carbonate (analytically pure) were weighed, mixed well and fed into a muffle furnace to be calcined at 500 ℃ for 2 hours. And cooling to obtain light gray powder, namely the carbon-based selenium material. 1012 g are weighed and analyzed by inductively coupled plasma mass spectrometry to determine that the selenium content is 58.10 ppm. The selenium balance of this process was calculated to be 93.3%.
100 G of the above carbon-based selenium material was charged into a plastic hose having a diameter of 10.0 mm l, and 5 l of brine (wherein the barium content was 8.10 ppm) taken from the north-su region was pumped in with a pump, and the total time for which the brine passed through the carbon-based selenium material was 5 hours. After inductively coupled plasma mass spectrometry analysis, the barium content in the filtered water was 0.43 ppm, and the barium absorption rate was 94.7%.
Example 2:
other conditions were the same as in example 1, but different weight ratios of selenoglycose to ammonium carbonate were used in preparing the materials, and the experimental results are shown in table 1.
Table 1 comparison of properties of materials synthesized with different weight ratios of selenoglucose to ammonium carbonate
From the above results, it was found that the material was substantially free of adsorption force to barium without adding selenoglycose (No. 1, 2). Only selenoglucose was added without ammonium carbonate, and the adsorption activity of the material to barium was also low (No. 3). Only by adding a proper proportion of selenoglucose and ammonium carbonate, the material has a good barium adsorption capacity, wherein the weight ratio of selenoglycose to ammonium carbonate is 1:3 (example 1). The use amount of ammonium carbonate is excessive, and the selenium balance and the adsorption force are reduced.
Example 3:
Other conditions were the same as in example 1, except that selenoglucose and calcium carbonate were used in different weight ratios in preparing the materials, and the experimental results are shown in table 2.
Table 2 comparison of properties of materials synthesized with selenoglucose and calcium carbonate using different weight ratios
From the above results, it was found that the material was substantially free of adsorption force to barium without adding calcium carbonate (No. 1). This is because selenium has no carrier, and the generated selenium carbon is aggregated into a very small block, which makes it difficult to perform the function sufficiently. Only by adding a proper proportion of selenoglucose and calcium carbonate, the material has good barium adsorption capacity, wherein the weight ratio of selenoglucose to calcium carbonate is 1:100 (example 1). When the calcium carbonate is insufficient, the total volume of the material is reduced, so that the adsorption effect is poor. If the calcium carbonate is excessive, the selenium concentration is lowered, which also results in poor adsorption effect.
Example 4:
The other conditions were the same as in example 1, but the materials were calcined at different temperatures, and the experimental results are shown in Table 3.
Table 3 comparison of properties of materials prepared at different calcination temperatures
From the above results, it was found that the effect was optimal at the calcination temperature of 500 ℃. Below this temperature, the material is not sufficiently activated, resulting in a decrease in the adsorption force. Selenium loss is severe when the temperature is too high, and the adsorption force is reduced.
Example 5:
other conditions were the same as in example 1, except that materials were prepared at different calcination times, and the experimental results are shown in table 4.
TABLE 4 influence of calcination time on the properties of the prepared materials
From the above results, it was found that the effect was optimal when the firing was conducted for 2 hours (example 1). The calcination time is short and the material is not sufficiently activated, resulting in a decrease in the adsorption force. If the calcination time is too long, the selenium loss is serious, and the adsorption force is reduced.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention in any way. Any simple modification, equivalent replacement, improvement, etc. of the above embodiments, which are made by those skilled in the art, are within the scope of the present invention, without departing from the technical spirit of the present invention.
