摘　　要：将马铃薯淀粉改性后,与聚合氯化铝铁复合,制备了淀粉基聚合氯化铝铁复合物(PAFC-CMPS)。通过FTIR、TG、SEM等手段对PAFC-CMPS的结构和表面形态进行了表征和分析。将PAFC-CMPS用于淀粉废水的处理,考察了絮凝时间、废水pH、絮凝剂加入量、温度等因素对PAFC-CMPS絮凝性能的影响。最佳实验条件下,絮凝剂对淀粉废水的COD去除率可达77.9%。Firstly, potato starch was modified by carboxymethyl group. Then it was composited with the polymeric ferric aluminum chloride, which afforded starch based polymeric ferric aluminum chloride composite （PAFC-CMPS）. The structure and apparent morphology of PAFC-CMPS were characterized by FT-IR, TG and SEM. PAFC-CMPS composites was applied as flocculant in treatment of wastewater. The effects of flocculation temperature, time, pH value and dosage on the flocculation activity were investigated. Under the optimum condition, the removal rate of COD reached to77.9%.
