| 摘 要： | 以氢氧化镧为共沉淀剂，对污水中锌、铜、镍、镉进行共沉淀分离富集后，用ＩＣＰ－ＡＥＳ法进行测定。在２５０ｍＬ污水中加入４．０ｍＬ镧溶液及３．０ｍＬ ＮａＯＨ溶液，使四种元素定量分离回收。测试结果表明，各元素的回收率在９８％～１０６％之间。

| Abstract: | Trace elements of Cu,Zn,Ni and Cd in the waste water are preconcentrated by La(OH)3 as corprecipitator and determined by ICP-AES.When 4.0 mL lanthanum solution(5 mg/mL) and 3.0 mL NaOH solution(5 g/L) are added in 250 mL volume of waste water,the recovery ratio of Zn,Cu,Ni and Cd are in the ranee of 98% ~ 106%. |
