| 摘 要： | 提出了直流示波极谱滴定高含量钼的新方法，在ｐＨ为４．５￣５．５的乙酸－乙酸铵缓冲溶液中，以Ｐｂ（Ⅱ）为滴定剂滴定钼酸根离子，用ＪＰ－１Ａ型示波极谱仪作检测器，根据滴定过程中铅波的出现来指示终点的到达。方法简便，快速，结果的准确度，精密度均符合容量分析的要求，适于各类高含量钼矿样中的测定。

| Abstract: | A new method for the oscillopolarographic titration of Mo(VI) is presented in this paper. The Mo(VI) in a buffer solution of HOAc-NH_1OAc at pH 4. 5~5. 5 is titrated with a standard solution of Pb(I) ion to form lead molybdate precipitate. Upon the complete precipitation of Mo( VI ) by the Pb ( I ) ion a sensitive and sharp Pb( I ) wave due to a slight excess of the titrating solution will appear on the screen of the JP-IA oscillopo-larograph which indicated the end point of the titration. The proposed method has been applied to the analysis of molybdenum concentrate. |
