| titleOfInvention | A kind of poly-aspartate bentonite composite material and preparation method thereof for heavy-metal ion removal |
| abstract | The present invention relates to water process formulation arts, disclose a kind of poly-aspartate bentonite composite material and preparation method thereof for heavy-metal ion removal.Poly-aspartate bentonite composite material is made by polysuccinimide, bentonite and silane crosslinker for raw material；The mass ratio of bentonite and polysuccinimide is 1:0.1-10, and the quality of silane crosslinker is the 1-10% of polysuccinimide quality；Polysuccinimide is made by the maleic acid that the mass ratio of the material is 1:0.9-1.7 and liquefied ammonia.Firstly, the present invention during preparing polysuccinimide using liquefied ammonia as nitrogen source, enrich the nitrogen source in polysuccinimide preparation process, also improve the utilization efficiency of nitrogen；Secondly low in cost using bentonite as raw material, it has excellent performance, and poly-aspartate is environmentally friendly material, can be amino acid small molecule by microorganism, fungus degrading, ultimately generate the water and carbon dioxide of environmental sound. |
