摘要
采用HNO_3+HClO_4混合酸溶解样品,ICP—AES测定冶金废水中的多种无机元素。方法检出限为0.00028～0.05μg/ml,样品加标回收率为92％～108％,RSD为0.41～23.6之间。
The sample was soluted by HNO3 + HclO3 mixed acid , and using ICP - AES to determine some inorganic elements in metallurgical waste water. This method's limit is 0. 00028～0. 05μg/ml,the sample with mark recovery ratio is 92%～108% ,RSD is among 0. 41～23. 6.
