Abstract
The invention discloses a bentonite-based copolymerized compound adsorbent. The bentonite-based copolymerized compound adsorbent is characterized by being prepared from the following raw materials in parts by weight: 120-130 parts of bentonite, 7-9 parts of crylic acid, 8-10 parts of vinyl acetate, 5-7 parts of maleic anhydride, 10-13 parts of calcium chloride, 8-10 parts of iron dihydrogen phosphate, 4-5 parts of modified diatomite and a suitable amount of water. By utilizing high chelation capability of a high-molecular chelating agent, the chelation capability of calcium chloride and iron dihydrogen phosphate and the high adsorption capability of bentonite, the bentonite-based copolymerized compound adsorbent disclosed by the invention has the characteristics of high adsorption capability, large adsorption capacity, high decolourization ratio to heavy metal ions and organic cationic dyes in wastewater, and the like. The bentonite-based copolymerized compound adsorbent can be used for adsorbing and removing the organic cationic dyes such as heavy metal ions and methylene blue in wastewater. By virtue of detection, the bentonite-based copolymerized compound disclosed by the invention has the advantages that the removal rate of silver ions in wastewater is 95.1% and the removal rate of methylene blue is 96.9%.
Description
Technical field
The present invention relates to a kind of modified function Material Field, relate in particular to copolymerized thing adsorbent of a kind of bentonite base and preparation method thereof.
Background technology
Along with industrial expansion, water pollutes day by day serious, is related to the future great cause of people's livelihood safety and motherland.Water treatment agent is varied, but much there is no specific aim, and cost is higher, needs further research adsorbent more targetedly, reduces costs, and reduces secondary pollution.
Summary of the invention
The object of the present invention is to provide copolymerized thing adsorbent of a kind of bentonite base and preparation method thereof.
Technical scheme of the present invention is as follows:
A copolymerized thing adsorbent, is characterized in that being made by the raw material of following weight portion: bentonite 120-130, acrylic acid 7-9, vinyl acetate 8-10, maleic anhydride 5-7, calcium chloride 10-13, primary iron phosphate 8-10, modification infusorial earth 4-5, water are appropriate;
