Determination and extraction of zinc from aqueous solution using ion-imprinted polymer
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 6
Abstract
Zinc is an environmental pollutant, which has been tested and assessed over the past few years from both the toxicological and human health viewpoints.At present study Imprinted polymer particles have been developed as a novel adsorbent for the adsorption of zinc from aqueous solution.Zinc-imprinted polymer was prepared with methacrylic acid (MAA) as the functional monomers, thleneglycoldimethacrylate (EGDMA) as the cross-linking agent, 2,2’-azobisisobutyronitrile (AIBN) as the initiator and Zn (II) ion as the imprint ion. The template Zn (II) ion was removed from the polymer by leaching with a liquid of a 1:1 volumetric ratio of HCl to ethylenediaminetetraacetic acid (EDTA). The capacity and selectivity of Zn(II) ion adsorption were investigated with the imprinted polymer and it’s nonimprinted counterpart. The polymer has a maximum adsorption capacity at pH 7.0. The isotherm of their batch adsorption of Zn(II) ions shows a Langmuir adsorption pattern. Imprinted polymer have a much higher capacity and higher selectivity of Zn(II) adsorption than non-imprinted ones. The limit of detection of the proposed method was 0.13 ?g L-1 . This research showed that Ion imprinting can be a promising technique of preparing selective adsorbents to separate and preconcentrate metal in a medium of multiple competitive metals. The method was applied to the recovery and determination of zinc in water and waste water samples
