The activated carbon can efficiently adsorb methylene blue in wastewater. The method has the advantages of simple technique and favorable adsorption effect.
Description
Technical field
The present invention relates to a kind of efficient preparation method for removing waste water methylene orchid adsorbent, and in particular to a kind of to utilize
The biomass such as Pericarpium Musae are raw material, and Jing chemical activation process prepares absorbent charcoal material, is that adsorbent is efficiently removed in waste water with which
The new method of methylene blue.
Background technology
In recent years, with China's weaving, the news speed development of printing and dyeing industry, the discharge capacity of waste water from dyestuff gradually increases, waste water
Not only there is specific color, and complex structure, most dyestuffs carry complicated aromatic ring structure, and with certain biology
Characteristic of concentration and toxicity, while which is difficult to be degraded under field conditions (factors), the environmental problem that waste water from dyestuff pollution causes becomes increasingly
It is prominent.Wherein it is difficult to degradation of organic substances and poisonous composition are a lot, some compositions have carcinogenic teratogenesis to human body.Methylene
Indigo plant is the dye of positive ion, with application widely, while also resulting in human body there are some bad reflections, such as jaundice,
Suffer a shock, palpitate quickly, vomitting, quadriplegia and tissue necrosiss etc..How safely and effectively to process waste water is to administer water dirt at present
The sixty-four dollar question of dye.Therefore the process of waste water from dyestuff has become the Important Problems of current water process research.For pre- waterproof
Body pollution, solves the problems, such as discharge of wastewater, and current sewage disposal method mainly has absorption method, electrochemical process and bioanalysises
Deng.Wherein adsorb the method that rule is wherein most Cheap highly effective, a critically important part is adsorbing material in absorption method, and active
Carbon Materials have good Jing as the pore structure with larger specific surface area and prosperity is as a kind of efficient adsorbent
Ji benefit and environmental benefit.
Patent CN105601057A discloses a kind of method for processing wastewater containing methylene blue, and which comprises the following steps：Will
Surfactant is mixed to get mixture with wastewater containing methylene blue, adds calcium salt to be reacted in the mixture, is subsequently adding
Flocculant carries out flocculation sediment, completes the process to methylene blue in waste.Patent CN105107463A discloses a kind of phosphorus tungsten
The preparation of sour composite and to methylene blue adsorption number performance test method, with Dawson types H6P2W18O62And metallic organic framework
MOF-5 is raw material, using solvent hot preparation adsorbent H6P2W18O62/ MOF-5 composites, study which to aqueous solution methylene
Blue absorption property.Patent CN103408093A discloses a kind of nano material quick adsorption and efficient desorption at ambient temperature
The method of methylene blue, concretely comprises the following steps：In the presence of a certain amount of sodium borohydride, 50 milligrams of adsorbents are only needed 10 minutes just can be by
In 100 milliliters of 100 milligrams per liter of methylene blue solutions more than 95% it is dye adsorption in adsorbent surface；Collected with external magnet and inhaled
The attached adsorbent of dyestuff, places in a small amount of water, adsorbs the dyestuff in adsorbent surface and starts quickly to be desorbed in solution, and
Desorption rate can reach more than 85%.Patent CN105601057A discloses a kind of method for processing wastewater containing methylene blue, including
Following steps：Surfactant and wastewater containing methylene blue are mixed to get into mixture, add calcium salt to carry out instead in the mixture
Should, being subsequently adding flocculant carries out flocculation sediment, completes the process to methylene blue in waste.
In above patent, the preparation cost of sorbent material is higher, therefore with biomass such as discarded Pericarpium Musae as raw material system
Getting everything ready has the activated carbon of certain absorption property significant.
