摘　　要：针对某铜盐厂硫酸铜产品杂质钙含量较高的现状,选用P204从硫酸铜溶液中萃取钙。考察P204质量浓度、相比O/A、萃取时间、水相平衡pH等对铜钙萃取分离的影响。结果表明,P204萃取钙的适宜条件为:P204质量浓度1.2mol/L,O/A=5∶1,振荡时间3min,pH=1.5。四级逆流萃取后,水相中钙质量浓度低于0.05g/L。P204 was chosen to extract calcium from copper sulfate solution, taking high calcium of impuri- ties in copper sulfate products into consideration. The effects of P204 mass concentration, O/A, extraction time, and equilibrium pH value of aqueous phase on separation of copper and calcium were investigated. The results show that the optimum conditions of P204 extraction include P204 mass concentration of 0.9 mol/L, O/A=5 ： 1, oscillation time of 3 min, and pH value of 1.5. The calcium mass concentration in water phase is below 5 mg/L after 4-stage countercurrent extraction.
