摘　　要：以包夹有丁二酮肟的PVC膜粘附在717强碱性阴离子交换树脂上为固定相,萃取色谱法分离富集矿样中的微量钯,以10%乙二胺 2%氢氧化钠溶液洗脱,用原子吸收光谱法测定。方法回收率在92.4%～98.9%之间。The separation/preconcentration method for palladium in ore by using PVC membrane containing dimethylglyoxime, physically loaded on 717 strong basic ion-exchange resins as stationary phase, was developed in this paper. Palladium was eluted using 10% glycol and 2% sodium hydroxide as eluant, and then determined by atomic absorption spectrometry. The recovery of palladium was 92.4%～98.9%.
