| Abstract: | 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 condi tions of the amount of bromine water.This method reduced the pretty long operation steps of the sulfuric acid smoke,and dissolved time of samples. |
| Keywords: | iodometric copper concentrates bromine water |
