摘要：以丙烯酰胺（AM)与甲基丙烯酰胺丙基三甲基氯化铵（MAPTAC)为共聚单体，通过紫外光引发聚合法制备阳离子聚丙烯酰胺絮凝剂P(AM-MAPTAC）。道过红外光谱（IR)与差热一热重分析(TG/DSC)分别对P(AM-MAPTAC)进行结构表征与热稳定性分析，并采用响应曲面法得到优化制备条件：反应体系pH为4.75，引发剂v-044质量分数为0.07%，EDTA-2Na质量分数为 0.20%，n(MATPAC)/n(AM)为0.33，光照时间为60min。在优化条件下制备P(AM-MAPTAC) 絮凝剂，特性粘度可达14.72dL/g，通过污泥脱水实验可验证该特性粘度下的污泥脱水效果最好，滤饼含水率（FCMC)达70%，污泥比阻（SRF）达6.94X101m/kg，上清液剩余浊度达9.70NTU，污泥脱水效果优于市售常用絮凝剂。

Abstract:The cationic polyacrylamide flocculant P（AM-MAPTAC)was prepared by polymerizing acrylamide （AM) and methacrylamide propyl trimethyl ammonium chloride （MAPTAC) under UV irradiation conditions. Determination the structural features and thermal stability of P(AM-MAPTAC) by IR and TG/DSC. The Response Surface Method was used to obtain the optimum preparation conditions: pH 4.75,initiator mass fraction 0.07%,EDTA-2Na mass fraction 0.20%,MATPAC/AM molar ratio O.33, illumination time 6Omin. Under optimal conditions, the intrinsic viscosity of P(AM-MAPTAC) reached 14. 72dL/g, under this condition, P(AM-MAPTAC) showed the best effect of sludge dewatering
