| titleOfInvention | Preparation of magnetic imprinting crosslinking AA/AM/BA grafting esterification cyanoethyl cassava starch microspheres and adsorption of copper ions |
| abstract | The invention discloses a preparation method of magnetic imprinting crosslinking AA/AM/BA grafting esterification cyanoethyl cassava starch microspheres and an adsorption method of the microspheres on copper ions. Firstly, synthesizing crosslinked AA/AM/BA-g-xanthate esterified cyanoethyl cassava starch by using cassava starch as a raw material, and wrapping ferroferric oxide into a starch derivative by using the crosslinked AA/AM/BA grafted esterified cyanoethyl cassava starch to prepare magnetic modified starch microspheres; and crosslinking the magnetic modified starch microspheres with metal ions by using a molecular imprinting method to obtain the magnetic imprinted polymer with selective adsorption. Adsorption of Cu 2+ The ion performance test shows that the microsphere has adsorption capacity Q =25.96mg/g，Cu 2+ Removal rate R = 98.11%. The product of the invention has good space network structure, increased specific surface area, selective adsorption and Cu resistance 2+ Has excellent adsorption performance. The method has high application value in the aspects of industrial sewage purification, heavy metal adsorption and the like. |
