摘　　要：报道了以GDX5 0 1(二乙烯苯和丙烯腈的聚合物 )型树脂浸渍磷酸三丁酯 (TBP)为固定相 ,用萃取色谱法使微量铂、金与常见贱金属分离。富集在色谱柱上的铂与金分别用 0 .2 5mol LHNO3 0 .5mol LNaClO3溶液和 0 .1mol LHCl 0 .2mol L硫脲溶液连续洗脱并用原子吸收光谱法进行测定。铂与金的回收率分别为 89.5 %～ 113.9%和 90 .1%～ 10 5 .3%By means of extraction chromatography, the micro amounts of platinum and gold were separated from the common metal elements successfully. Using GDX501 resin dipped tributyl phosphate as stationary phase. Platinum and gold preconcentrated in chromatographic column were eluted using 0.5 mol/L HNO3-0.5 mol/L NaClO3 and 0.1 mol/L HCl-0.2 mol/L thiourea as eluant respectively, and then separation and determination were carried out. The recoveries of platinum and gold were 89.5% similar to 113.9% and 90.1% similar to 105.3% respectively.
