The liquid-liquid extraction of copper (II) using a novel extractant LIX 984N (a mixture of 5-nonylsalicylaldoxime and 2-hydroxy-5-nonyl-acetophenone oxime) was carried out. Following the liquid-liquid extraction, coupled uphill transport of copper(II) across a bulk liquid membrane containing LIX 984N as carrier was performed. The effects of aqueous stirring speed, carrier concentration, and inventory of membrane liquid were investigated. The rate-limiting step for the coupled transport of copper across a bulk liquid membrane was identified.
