| Abstract: | This paper provided a titration method for determination of total iron in the bioleaching solution.This method is based the reduction of Fe3＋ by SnCl2 with methyl orange as indicator,and then the sample solution is titrated by potassium dichromate standard solution with diphenylaminesulfonic acid sodium salt as the indicator.It was found that normal purple color can not be observed at the end point and error will be introduced sometimes.In this work,this phenomenon was investigated and the method was greatly improved. |
| Keywords: | Bioleaching Potassium dichromate Titration method Total iron |
