实验发现,在散射光中Fe(Ⅱ)-BPT络合物能发生显著的光还原反应,产生Fe(Ⅰ)-BPT络合物,上述反应在NaH_2PO_4-Na_2HPO_4缓冲液中进行缓慢。此法可用于铁矿中铁的价态分析。分析结果与标准值一致。
It was found that Fe (Ⅱ) -BPT complex could undergo a significant photoreduction reaction in the scattered light to produce Fe (Ⅰ) -BPT complex, and the reaction proceeded slowly in NaH 2 PO 4 -H 2 PO 4 buffer. This method can be used for the valence analysis of iron in iron ore. The results of the analysis are consistent with the standard values.
