| Abstract: | The cationic starch flocculant bearing quaternary ammonium groups was synthesized using natural polymeric starch as raw material and 3-chloro-2-hydroxypropyl-trimethyl ammonium chlorate as cationic etherifying agent by microwave Radiation in dry process. The flocculant has good flocculation and bactericidal function. The effects of miscellaneous factors on synthesis were investigated and the optimum conditions were determined from orthogonal test. The result showed that the relative viscosity of product was 3.18 and the degree of cation substitution was 0.31 when the molar ratio of cationic etherifying agent to starch was 0.35, the molar ratio of NaOH to cationic etherifying agent was 1.2, microwave power was 184?W, and the radiation time was 3?min. |
| Keywords: | cationic starch quatemary ammonium salt microwave dry process flocculant bactericidal action |
