摘　　要：以淀粉为原料、3-氯-2-羟丙基三甲基氯化铵为阳离子醚化剂,采用湿法制备阳离子淀粉。考察了pH、吸附剂用量、吸附时间和吸附温度等因素对吸附效果的影响。室温下,阳离子淀粉对含磷模拟废水的吸附工艺条件为:pH为3.0,吸附剂用量为12.0 g/L,吸附时间为2.0 h。在上述条件下,阳离子淀粉对磷的去除率可达90.41%。Cationic starch was prepared via reaction of starch with 3-chlorine-2-hydroxypropyl trimethylammonium chloride by wet-process.Effects of pH,adsorbent dosage,adsorption time and temperature on adsorption efficiency were investigated.At room temperature,the optimal adsorption condition of cationic starch for simulated phosphorus containing wastewater was： pH 3.0,adsorbent dosage 12.0 g/L,adsorption time 2.0 h,under this condition,removal rate of cationic starch for phosphorus could up to 90.41 %.
