摘　　要：采用共沉淀泡沫分离法对水中钴离子的去除进行了研究,考察了表面活性剂种类及质量浓度、pH值、铝钴摩尔比、气流量等因素的影响.当水中的钴离子初始质量浓度为10 mg.L-1,采用SLS做表面活性剂且质量浓度为10 mg.L-1,铝钴摩尔比为1∶1,pH值为11,气流量为300 L.h-1时,去除率可达97.61%.The cobalt ion in water was separated by using precipitation foam separation. The influences of surfactants, pH value, the mole ratio of aluminium to cobalt, the concentration of surfactant and gas flux were studied. The removal efficiency is 97.61% when the concentration of cobalt ion is 10 mg L^-1 , the concentration of sodium dodecyl sulphate is 10 mg L^-1, the mole ratio of aluminium to cobalt is 1：1 , pH value is 11 , and gas flux is 300 L ·h^-1.
