Description
Summary:The ability of the synthesized CTA-Aliquat 336 Polymer Inclusion Membranes (PIMs) for removing heavy metal ions (Cd2+, Zn2+ and Fe2+) from aqueous solution were investigated. This study provides important kinetic data necessary for adsorption of different heavy metal ions on CTA-Aliquat 336 PIMs. The kinetic studies were evaluated by simulating the data using Legergren first order kinetics model. The uptake kinetic of Cd(II), Zn(II) and Fe(II) in PIMs containing different concentration of Aliquat for various duration was quantified. The maximum adsorption uptake of Cd2+, Zn2+ and Fe2+ were found to be 7.4, 6.7 and 1.7 mg/g respectively after 2 hours at the 50 wt.% of Aliquat 336 concentration. In the absence of Aliquat 336, there is no significant metal uptake in CTA-Aliquat 336 PIMs which can served as an effective barrier to ion permeation.
