邻二氮菲分光光度法测定金属锑中铁含量

Determination of Iron Content in Stibium by Ortho-dinitrogenous Phenanthrene Spectrophometry

用王水溶解金属锑 ,以酒石酸钾钠为络合剂 ,盐酸羟胺为还原剂 ,在波长 5 1 0nm处以邻二氮菲分光光度法测定铁的含量。

Metal Stibium was dissoluted by aqua regia , sodium and potassium tartaric was used as complexant, hydroxylamine was used as reductant, the determination was done at 510 nm. This method was very accurate.
