摘要
络合萃取法分离极性有机物稀溶液具有高效性和高选择性。负载溶剂的再生是络合萃取过程中的重要步骤,它直接影响分离过程的经济可行性。综述了络合萃取中的“摆动效应”,讨论了利用“摆动效应”的负载溶剂再生过程。
The extraction technique based on reversible chemical complexation is characteristic of high capacity and high selectivity.As an important step to apply the said technique,the regeneration of solvent loaded strongly influences the economic viability of the separation process.In this paper,several swing effects,including pH swing, pH swing with a volatile base,temperature swing and diluent composition swing,are critically reviewed.The regeneration processes of solvent loaded with swing effect are discussed.
