碘量法测铜精粉铜含量的条件实验

摘要

用碘量法测铜精粉中铜的含量,用溴水和硝酸替代饱和氯酸钾的硝酸溶液溶样,并对溴水的用量做条件实验,减少了硫酸冒烟这一比较漫长的操作步骤,缩短了溶样时间.%The copper content in copper concentrates by iodometric was determined, using bromine water and nitric acid replace saturated potassium chlorate nitric acid solution to dissolve samples, and testing the experiment conditions of the amount of bromine water. This method reduced the pretty long operation steps of the sulfuric acid smoke, and dissolved time of samples.
