The extraction of Cadmium (II) (Cd(II)) ions across a Supported Liquid Membrane (SLM) using Triethyleneamine
(TEDA) in Carbon tetrachloride (CCl4) as a carrier, was investigated. The aforementioned carrier was embodied
within the microporous polypropylene membrane. Hereby, we present the results of optimization of certain conditions
like acid and carrier concentration in feed and membrane phase respectively, stripping phase makeup, and their
effects on stripping of the metal ions from the feed solution. 1.0 M HNO3 in the feed solution, 1.5 M in stripping
phase, 3.75 M of TEDA in membrane phase and 2.36 × 10-3 mol/dm3 of Cd(II) metals ions concentrations were found
to be the optimum conditions for the extraction of Cd(II). Some theoretical equations were proposed which were
beneficial in investigating the extraction mechanism and stoichiometry of the physio-chemical processes occurring
in the organic membrane phase. Characterization of the SLM through flux, permeability and diffusion coefficient and
an investigation into its stability for applications in the industry were also carried out.
