Abstract

Abstract:

The［BPy］［PF₆］-TBP-C₂H₄Cl₂ extraction system was constructed by using tributyl phosphate（TBP） as extractant，N-butylpyridine hexafluorophosphate（［BPy］［PF₆］） as coextractant，and dichloroethane（C₂H₄Cl₂） as diluent to separate lithium ions in salt lake brine.The effects of water phase acidity，ionic liquid concentration，TBP concentration，and other factors on the lithium extraction efficiency were investigated by single factor experiments.The results showed that the optimal conditions of the extraction system were as follows：the concentration of ionic liquid was 0.3 mol/L，the volume fraction of TBP was 60%，and the ratio of O/A was 2.5/1.Under these conditions，single-stage extraction efficiency of 91.65% for Li⁺ and 5.86% for Mg²⁺ were obtained，and this extraction system showed good selectivity for Li⁺.The thermodynamic study showed that the extraction reaction of lithium ions by the ionic liquid system was a spontaneous exothermic reaction.This experimental study provided a certain basis and reference for the extraction and separation of lithium ions in the ionic liquid system.
