Polymer Inclusion Membrane (PIM) as Competitive Material for Applications in SPE for Water Treatment Process
Abstract: The elaboration of a polymer inclusion membrane (PIM) and solvent impregnated resin (SIR) XAD7 with sorptive characteristics intended for removal of heavy metals was investigated. Bis (2,4,4-trimethylpentyl) monothiophosphinic acid (Cyanex 302) was used as an acidic extractant. The sorption of Zn(II), Cu(II) and Fe(II) ions onto the PIM and SIR was investigated and optimized as a function of contact time, pH, extractant amount and concentration of metal ions. Both the PIM and the SIR showed reasonably good ability for the separation of metal ions from ternary mixture. The elution of the metal from the PIM and SIR was accomplished (100% and 90% for PIM and SIR respectively) with 1.0 M HNO3. The elution treatment allows both the polymers to be reused.
