薄层色谱是晚近才广泛用于分析实际中的一种微量技术;虽然由于它的某些优点使它在有机分析中已获得广泛应用,但关于无机薄层色谱的报导尚不很多。铂族元素及金的薄层层析研究,迄今似尚未见诸文献。我们对铂族元素及金在硅胶-煅石膏薄层上的色层分离行为作了较多的试验后,得到下列结果:用丙酮-浓盐酸-醋酸乙酯(100:1:100,V/V/V)作 Thin layer chromatography (TLC) is a trace technology that has been used extensively in the analysis of practice recently. Although it has been widely used in organic analysis due to some of its advantages, there are not many reports on inorganic thin layer chromatography. Platinum group elements and gold thin layer chromatography study, so far seems to have not seen the literature. After more experiments on the color separation of platinum group elements and gold on the thin layer of silica-calcined gypsum, the following results were obtained: using acetone-concentrated hydrochloric acid-ethyl acetate (100: 1: 100, V / V) for
