| Abstract: | Copper precipitation method is by pH adjusting,then adding ammounium bifluoride to eliminate the interference of iron,by sodium hyposulfite titration and starch indicator solution.The paper discusses application the copper conternt precipitation using fast titration method in metal mine.The method is quick and easy to master,and the result are confirmed,so the method is suitable for the copper detemination in the metal mines. |
