Abstract:: This article studies the light reduction conditions of Fe (ⅢL) -Phen and Fe (III) -Phen -Edta system. Experiments found that when high -pressure mercury lamps are irradiated, the 100 ～ 300 μgfe in the upper system can be restored to Fe (Phen) _3 ~ (2+) in 6 to 15 minutes. This light reduction method is used for the analysis of the iron in the GSD -1 standard ore. The results are the same as the recommendation value.
