本文研究了Fe(Ⅲl)—phen和Fe(Ⅲ)—phen—EDTA体系的光还原条件,实验发现当用高压汞灯液内照射时,上体系中的100～300μgFe在6～15分钟能被还原为Fe(phen)_3~(2+)。这种光还原方法用于GSD—1标准矿样中铁的分析,其结果与推荐值一致.
In this paper, the photoreduction conditions of Fe (Ⅲl) -phen and Fe (Ⅲ) -phen-EDTA systems were studied. It was found that 100 ~ 300μg Fe in the upper system can be Reduction to Fe (phen) _3 ~ (2+). This photoreduction method is used for the analysis of iron in the standard sample of GSD-1. The result is consistent with the recommended value.
