摘　　要：以玉米淀粉和丙烯酰胺为原料,高锰酸钾为引发剂,采用微波辐射法制备淀粉接枝丙烯酰胺聚合物(S-g-PAM),用红外光谱对产物进行表征,并研究了其对印染废水的处理效果。通过正交试验得到优化的S-g-PAM制备工艺条件为:微波处理温度50℃,微波处理时间20 min,引发剂浓度1.8 mmol/L,单体淀粉质量比为2∶1,p H=3。在此条件下,S-g-PAM接枝率达143.41%。微波辐射聚合制备S-g-PAM时间短,接枝率高,处理印染废水时投加量少,易生物降解,费用低。Using corn starch and acrylamide as raw materials, potassium permanganate as initiator, starch-grafted acrylamide polymer （S-g-PAM） is prepared under microwave radiation, and the product is analyzed by FTIR. Through orthogonal experiment, the optimal preparation process of S-t-PAM is temperature of microwave treatment 50 ℃ and time 20 min, initiator concentration 1.8 mmol/L, the mass ratio of starch to monomer 2： 1, pH value 3, and the graft ratio of S-g-PAM reaches 143.41%. Microwave irradiation-assisted preparation of S-g-PAM features shorter time, higher grafting ratio, lower dosage of treatment for dyeing wastewater, which is easy degradation and low cost.
