【摘要】 以硅胶G-羧甲基纤维素（CMC）为固定相,正丁醇/甲基异丁基酮（MIBK）/二（2-乙基己基）-磷酸酯(P₂₀₄)/盐酸为流动相,用薄层色谱法分离贵金属。结果表明,正丁醇/MIBK/P₂₀₄/HCl 为140∶100∶15∶18（v/v）时,Au、Pd（Pt）、Ru、Ir 和 Rh 可完全分离;在140∶100∶15∶1（v/v）时,Pt 和 Pd 可分离,其它几个元素不干扰。结果满意。更多还原

【Abstract】 We have studied the separation of noblemetals on silica G-CMC plates with a mixtureof n-butanol,methyl isobutyl ketone,P₂₀₄（di-（2-ethylhexyl）phosphate）and hydrochloric acid ofvarious ratios as mobile phase.With ratio of140:100:15:18（v/v）,Au,Pd（Pt）,Ru,It andRh can be separated,and the separation of Ptand Pd can be carried out at the ratio of 140:100:15:1（v/v）.The presence of other noblemetals did not interfere the determination.更多还原
