摘要
采用了无汞测铁技术应用于铬铁矿中全铁的测定新方法。用甲基橙作SnCl2还原Fe3+的指示剂,再用K2Cr2O7标准溶液滴定亚铁。试验结果表明,该法简单、快速、准确可靠对环境无汞污染。
A new analytical method for whole iron in chromite was introduced, which used the tecnmque oi iron measurement without mercury. Metyl orange used as the indicator deoxidized Fe^3＋ with the SnCl2, then titration Fe^2＋ with standard aqua K2Cr2O7. The experiment results indicated that this method was accurate, simple and efficient without mercurial pollution to the environment.
