| 摘 要： | 试样用硝酸－硫酸分解，试验了酸度、还原剂浓度以及黄铜中常见元素对测定结果的影响，砷、锑的回收率分别为：９６％～１０９％，９０％～９３％，砷、１锑的检出限分别为０．１９ｎｇ＝ｍＬ、０．３１ｎｇ＝ｍＬ，砷、锑的线性范围分别为０．５～２５０ｎｇ／ｍＬ、０．５～５００ｎｇ／ｍＬ。本法用于黄铜标准样品中的砷、锑。结果与标准值吻合。

| Abstract: | The sample was dissolved by HNO 3 H 2SO 4,the effect of the concentration of acid and reducing agent and interferences from common coexisting elements on the determination of As and Sb were tested. The precision,recovery and detection limits of the method are satisfactory,the method was applied to the determination of As,Sb in brass standard reference , the result is in conformity with the standard value |
