摘要
A liquid membrane process for removing ions from solution which comprises contacting a solution containing a first ion and a second ion with an emulsion, said emulsion comprising an external phase which is immiscible with said solution and contains a first complexing agent, and a second complexing agent, said first complexing agent being capable of forming a first complex with said first ion, and said second complexing agent being capable of forming a second complex with said second ion, both of said complexes being soluble in said external phase, and an internal phase, which comprises a (1) decomplexing agent, said decomplexing agent being capable of converting said first complex into said first complexing agent and said first ion and (2) an inhibiting agent which is capable of inhibiting the formation of said first complex, whereby the first ion diffuses from said solution into said internal phase, and said second ion diffuses from said solution into said external phase.
