摘要
本文研究胺醇萃取剂ＴＡＢ－１９４在盐酸介质中萃取钯时稀释剂、萃取剂浓度、萃取平衡时间的影响．用ＨＮＯ＿３反萃取钯．用连续变化法、饱和法及元素分析法确定了萃合物的组成．萃取体系的界面性质研究表明，萃取反应主要在界面上进行，通过红外光谱、紫外光谱确定了萃取机理为离子缔合．
The extraction of PdCl2-4 from hydrochloric acid with TAB-194 wasstudied. The optimal conditions of extraction and reextraction were determinedexperimantally. The composition of the extracted complex was studied by methods ofsaturation,molecular ratio,and elementary analysis. The mechanism of extraction isregarded as ion-association. It was found that the extraction reaction were taken placemainly on the interface, concluded from the study on the TAB-194HHCl interfacialnature.
