摘要：
A liquid membrane containing 4% di-2-ethylhexyl phosphoric acid and 5% sorbitan monooleate in kerosene is used in the form of an emulsion for the simultaneous extraction and concentration of cadmium and manganese from aqueous solutions. When 4% tri-n-octylamine is included in the membrane composition, only manganese is extracted while cadmium remains in the sample solution. The extracted elements in the concentrate are recovered by breaking the emulsion with n-butanol. Recoveries of cadmium and manganese range from 92-104% for 60-ml samples containing 2-9-mu-g of each element.
