摘　　要：进行了Fe(Ⅲ)-草酸盐配合物体系对含Hg(II)的模拟废水的光化学还原处理研究,当pH=5.0时,Hg(II)光化学还原效率最好。在实验选择的[Fe(Ⅲ)]和草酸盐浓度范围内,Fe(Ⅲ)和草酸盐浓度的增加能提高Hg(II)的光化学还原效率。CH3OH也能提高Hg(II)的光化学还原效率。In this paper, the photochemical reduction process of Hg（Ⅱ） in aqueous solutions containing ferric and oxalate （Ox） was studied. It was showed that, when pH=5.0, Hg（Ⅱ） photoredction efficiency was the highest; within the concentration of [Fe（Ⅲ）] and oxalatc selected in the experiment, the increases of the concentration of Fe（Ⅲ） and oxalate could heighten Hg（Ⅱ） photoreduction efficiency, and CH3OH could do so as well.
