英文摘要	以金属铝板为阳极,金属铁板为阴极,0.1 mol/L的AlCl3水溶液作电解液,应用与重力方向平行的外加磁场耦合直流电解法合成聚合氯化铝(PAC).在磁通密度0.4 T,相邻电极间距15 mm,电解槽电压2.4V,电流密度300 A/m2下,成功制备出盐基度Ba=2.4,总铝含量(AlT)为0.6 mol/L,有效絮凝成分Al13占AlT83.2%的PAC产品,其电压效率85.2%,电能效率81.5%,比电极面积为140.1 m2/m3.恒流法测试表明,磁场对电极极化有抑制作用,并可增大电极表面膜溶解速率,且随磁通密度增加而增强.; Polyaluminum chloride(PAC) was prepared by electrochemical process coupled with magnetic field paralleling to the gravitation direction.The electrolyte of 0.1 M AlCl3 solution was used,with the iron plates as cathode and aluminum sheets as anode.PAC of 0.6 M total aluminum(AlT),83.2% Alb to AlT and basicity(Ba)=2.4 was synthesized when magnetic flux density was 0.4T,the distance of electrodes was 15 mm,the voltage of electrolysis cell was 2.4 V and current density was 300 A/m2.Under above experimental conditions,the voltage efficiency,energy efficiency and electrodes surface area to reduction cells of electrochemical reactor were 85.2%,81.5% and 140.1m2/m3,respectively.The polarization curves determined by constant-current method showed that the presence of magnetic flux density had prohibited the electrodes from polarization and increased the matter dissolution rate of the electrodes which was strengthened with the increased intensity of magnetic field.; 作者联系地址：湖北工业大学化学与环境工程学院;武汉理工大学资源与环境工程学院;; Author's Address: 1.College of Resources and Environmental Engineering,Wuhan University of Technology,Wuhan 430070,China;2.College of Chemical and Environmental Engineering,Hubei University of Technology,Wuhan 430068,China
