摘　　要：为有效去除水体中Mn(Ⅱ)和溶解性有机物(DOM),以聚合硫酸铝铁(PAFS)和聚丙烯酰胺(PAM)-谷胱甘肽(GSH)为原料,成功合成复合混凝剂PAM-GSH-PAFS,对产物结构和组成进行了表征,并对其混凝性能进行了研究。结果表明:PAFS与PAM-GSH发生了化学反应;PAM-GSH-PAFS具有复杂紧密的孔隙结构,有助于产生吸附架桥和网捕卷扫作用,表现出优异的混凝性能。当Mn(Ⅱ)与溶解性有机碳(DOC)均为10.0mg/L,pH为7.0,PAM-GSH-PAFS投加量为5.76mg/L时,Mn(Ⅱ)与DOC去除率分别达到63.5%、82.4%。In order to remove Mn(Ⅱ)and dissolved organic matter(DOM)in water,polymeric aluminum ferric sulfate(PAFS)and polyacrylamide(PAM)-glutathione(GSH)were obtained as raw materials to synthesize the composite coagulant PAM-GSH-PAFS successfully.The structure and composition of the product were characterized and the coagulation properties were studied.The results showed that PAFS had chemical reaction with PAM-GSH,PAM-GSH-PAFS had complex and compact pore structure,which was conducive to adsorption bridging and net rooling-sweeping,indicating excellent coagulation performance.When the mass concentrations of Mn(Ⅱ)and dissolved organic carbon(DOC)were both 10.0 mg/L,pH was 7.0,dosage of PAM-GSH-PAFS was 5.76 mg/L,the removal rates of Mn(Ⅱ)and DOC were 63.5% and 82.4%,respectively.
