摘 要：<正> It is indicated from a study of transport of rare earth ions through the emulsion liquid mem-brane of bis（2,4,4-trimethylpentyl）phosphinic acid-Span 80-toluene that transporting rare earth ions com-pletely and rapidly was realized under the optimum experimental conditions:1.0×10-3～3.0×10-3mol/Lbis（2,4,4-trimethylpentyl）phosphinic acid and 2%～4%（W/V）Span 80 in toluene solution as membranephase,0.50～2.0 mol/L HCl as inner phase,rare earth ion solutions with pH 3.5～5.0 as outer phase.Ac-cording to the differences of transport behavior for rare earth ions,it is possible to separate rare earth ionsfrom mixed solutions of rare earth ions by this liquid membrane system.
