摘要
对黄金冶炼厂含氰废水中氰化物的检测方法进行了研究,确定了镍标准溶液滴定分析氰化尾液中氰化物的较优分析条件,并对银量法、溴水氧化—碘量法和镍标准溶液滴定法进行了对比,结果表明镍标准滴定法操作过程简单,准确度和精密度较高,适用于氰化尾液处理过程以及浸出过程中氰化物的在线分析.
The paper deals with the cyanide in the cyanide-bearing waste water and the best condition for the nickel volumetric analysis cyanide is made. Meanwhile contrast is made between Ag volumetric and bromine oxidation—iodine method. The result shows that the nickel volumetric analysis is easy operating,with high accuracy and definition. It adapts to the cyanide on-line analysis of the course in recovering cyanide of cyanide-bearing waste water in gold leaching.
