| Abstract: | This paper reports a new method for analyzing whole iron in diamond wheel which uses the technique of iron measurement without mercury.Fe3+ is deoxidized with the SnCl2 using methyl orange as the indicator,then titrating Fe2+ with standard solution K2Cr2O7.The experiment results indicated that this method is accurate,simple and efficient without mercurial pollution to the environment. |
