摘要
Abstract
A new amphoteric phosphate cationic starch was synthesized with a low substitution degree of starch phosphate ester and cationic etherifying agent as raw material, which was applied in printing and dye⁃ing wastewater treatment. The effects of pH, reaction time, reaction temperature and the dosage of cationic etherification agent in the etherification reaction system on the substitution degree were investigated. The opti⁃mum reaction conditions were determined as fol ows: reaction system pH=11, reaction temperature 40 ℃, re⁃action time 6 h. The chroma removal rates of printing and dyeing wastewater treated by cationic amphoteric starch phosphate with different cationic degree of substitution were tested. The results showed that amphoter⁃ic starch phosphate with 0.036 8 of anion substitution degree and 0.013 1 of cationic degree had the best de⁃coloration effect.关键词
