摘要
研究了硝酸亚汞在高价铬锰体系中对锰的选择性还原作用 ,据此建立了同时测定不锈钢中铬和锰的还原光度法 ,不锈钢中其它成分无干扰。方法简便快速 ,适合钢铁厂炉前分析。
In the system of high valence chromium and manganese the effect of selective reduction of mercurous nitrate on the manganese has been studied On this basis a new method for simultaneous spectrophotometric determination of chromium and manganese in stainless steel by the reduction has been developed The other compositions of stainless steel has not any interference on the determination The method was simple and quick,it meets the demands for the routine analysis in ferrous factory
