Abstract: | This paper studied that lead content in ores were titrated with 5-k-PADAP indicator and EDTA titrant inhexaniethylenamine medium(PH=5.5).The results of experimentation show that the color change at end point is verysharp and the variation coefficient of determination result is 0.27%(n=5). |
