摘要：

A novel ionic liquid type saponification processing based on quaternary phosphonium type bifunctional IL was developed for yttrium separation from ion-adsorbed rare earth deposit.The extractabilities of([trihexyl（tetradecyl）phosphonium][sec-octylphenoxy acetate]([P6,6,6,14][SOPAA]) were pronouncedly higher than those of sec-octylphenoxy acetic acid（HSOPAA）,a mixture of HSOPAA and[P6,6,6,14]Cl for rare earth elements（REEs）.The ion association extraction mechanism contributed to avoiding the numerous saponification procedures using alkali and resulting in saponification wastewater.After 13 stages of extraction and 6 stages of scrubbing sections,the Y（Ⅲ） was successfully separated from industrial heavy RREs feed,the purity of Y（Ⅲ） in raffinate was approximately to be 98.9%.Stripping by distilled water was effectively achieved for REEs,which contributed to the decreased consumption of acid to a considerable extent.
