硝酸氯酸钾-硫酸消解测定锑矿盐酸-氯化物浸出液中锑量

Determination of Antimony Content in Chloridizing Leaching Solution of Stibnite by Nitric Acid-Potassium Chlorate-Sulfuric Acid Dissolution

文章采用硝酸氯酸钾-硫酸消解样品、硫酸铈滴定法测定锑矿盐酸-氯化物浸出液中锑含量。试验表明,较单纯的硫酸消解样品分析结果更稳定,锑的回收率更高,能够满足锑矿氯化浸出液中锑的检测要求。

The chloridizing leaching solution sample was dissolved by nitric acid-potassium chlorate-sulfuric acid with high temperature heating, titrated by cerium sulfate. Experiments show that, the analysis results of nitric acid- potassium chlorate-sulfuric acid dissolution is more stable than the only sulfuric acid dissolution, the recovery rate is higher, and it can meet the requirements of the determination of antimony in chloridizing leaehing solution.
