摘要
提出了一个快速测定金属铜中微量砷的新方法。采用铁氰化钾 -亚铁氰化钾沉淀分离基体铜等与微量砷相分离 ,并用催化示波极谱测定 。
A new method for the rapid determination of trace amounts of arsenic in metallic copper is described in this paper. The copper matrix is separated from arsenic and other co existing elements by precipitation with K 3[Fe(CN) 6] K 4[Fe(CN) 6]. Trace amounts of arsenic remained in the solution is determined by the catalytic oscillopolarographic method.
