Synthesis of Ionic Imprinted Polymer Particles for Selective Membrane Transport of Fe(III) using Polyeugenol as the Functional Polymer

Abstract

The preparation of Ionic Imprinted Polymer (IIP) particles for selective membrane transport of Fe (III) had been done using polyeugenol as functional polymer and PVA (polyvinyl alcohol) (Mr 125,000) solution in 1-Methyl-2-pyrrolidone (NMP) solvent as membrane base. The membrane was then cut and Fe(III) was removed by acid to produce IIP particles membrane. Analysis of the membrane and its constituent was done by IR, SEM and also TOC analysis. Experimental results showed the transport of Fe(III) was faster with the decrease of membrane thickness and the higher concentration of template. However, the transport of Fe(III) was slower for higher concentration of PVA (Polyvinyl Alcohol) in the membrane. The selectivity of all IIP particles membrane was confirmed as they were all unable to transport Cr (III), while NIP (Non-imprinted Polymer) membrane was able transport Cr (III).
