草酸铁(Ⅲ)(固相或溶液体系)的光化学分解的研究已有一些工作,但负载型草酸铁(Ⅲ)的光分解研究尚未见报道。吸附在载体表面上的化合物的性质与化合物本体的性质有很大的区别,载体表面化合物的研究对考察载体的作用,揭示其表面性质有重要的意义。本文用穆斯堡尔谱和气相色谱研究了活性炭、硅胶、γ-Al_2O_3和氧化镁负载的草酸铁(Ⅲ)的光化学分解。 There has been some work on the photochemical decomposition of iron (III) oxalate (solid phase or solution system), but the photodegradation of supported iron (III) oxalate has not been reported yet. The properties of the compound adsorbed on the surface of the carrier are quite different from those of the compound itself. The study on the surface compounds of the carrier is of great significance for examining the effect of the carrier and revealing its surface properties. In this paper, the photochemical degradation of iron (III) oxalate supported on activated carbon, silica gel, γ-Al 2 O 3 and magnesia was investigated by Mossbauer spectroscopy and gas chromatography.
