Emulsion Liquid Membrane Stability And Efficiency For Cadmium Removal Using Vegetable Oils

The application of Emulsion Liquid Membrane (ELM) in the extraction of cadmium ions was explored. ELM consists of internal and membrane phase that form the primary W/O (water-in-oil) emulsion which to be dispersed in the external phase. In promoting sustainable development, vegetable oil which is en...
