摘　　要：由马来酸(MA)和烯丙基磺酸钠(SAS)合成了不含磷氮的循环冷却水处理药剂MA/SAS共聚物。采用红外光谱、元素分析、凝胶色谱以及热重分析等进行表征,采用静态试验对共聚物的阻垢、分散以及生物降解性进行了研究,结果表明,其对碳酸钙、磷酸钙以及硫酸钙的阻垢率均可以达到100%,分散后上层清液透光率最低为35.4%,28 d生物降解率为63%,对环境友好,是一种很有发展前景的循环水处理剂。A phosphorus and nitrogen free circulating cooling water treatment agent,MA/SAS copolymer,was synthesised from maleic acid(MA)and sodium allyl sulfonate(SAS).The product was characterised by infrared spectroscopy,elemental analysis,gel chromatography and thermogravimetric analysis.The copolymer was investigated for scale inhibition,dispersion and biodegradability using static tests,which showed that the scale inhibition rate of calcium carbonate,calcium phosphate and calcium sulphate could reach 100%,the light transmission rate of the upper clear layer after dispersion was 35.4%,the biodegradation rate of 28 d was 63%.The copolymer is environmentally friendly and it is a promising circulating water treatment agent.
