Abstract

The correlation between the anions of the ionic liquids of BMIM⁺BF₄^-, BMIM⁺CF₃SO₃^- and BMIM⁺NO₃^- in poly(2-ethyl-2-oxazoline)/AgNO₃ membranes and reduction of silver ions has been investigated. The anion type negligibly affected the initial separation performances, however it significantly affected the long-term operation stability. Additionally, UV and TEM confirmed the long-term operational stability was strongly associated with the reduction rate of the silver ions. The reduction rate of the silver ions in the polymer/silver salt/ionic liquid complex was observed in following order: BMIM⁺BF₄^- > BMIM⁺CF₃SO₃^- > BMIM⁺NO₃^-, suggesting that among the ionic liquids investigated, BMIM⁺NO₃^- had the most improved separation performance.
