摘　　要：对测定废旧电池中铁、镉、铬、铅、锡和铜的样品预处理方法和检测条件进行了研究。在预处理过程中采用盐酸溶解,大大减少了金属元素的损失。运用标准加入法,ICP-AES同时测定铁、镉、铬、铅、锡和铜,线性范围为1—50m g/L,加标回收率在84.2%—102.3%,精密度为2.62%—4.92%。The sample pretreatment and conditions for determination of iron,cadmium,chromium,lead,stannum and copper in used battery were studied.The sample was dissolved in hydrochloric,which mostly reduced the loss of metals.Then the iron,cadmium,chromium,lead,stannum and copper in used battery were simultaneously determinated by ICP-AES with standard addition method,the linear range was 1—50mg/L and the recoveries were in the range of 84.2%—102.3%,the relative standard deviations were in the range of 2.62%—4.92%.
