|Title:||Synthesis of crosslinked poly(vinyl alcohol) and studies on its efficiency in zinc ion uptake from aqueous solution|
|Keywords:||Analytical Chemistry;Crosslinked polymers;Solid phase extraction;Zinc|
|Abstract:||Crosslinking of polyvinyl alcohol by methylene bis acrylamide has been carried out for binding Zn(II) cations from aqueous solution. Metal ion uptake capacity of the crosslinked polymer has been evaluated in the light of varying pH, temperature, time and concentration by batch equilibrium procedure. The polymer has been characterized by chemical, TGA and FTIR data. Surface morphology has been studied with the help of SEM images. Zn(II) has been isolated quantitatively from various synthetic mixtures containing metal ions (Ni(II), Cd(II) and Cu(II)) commonly found in the effluent of galvanization industry. The method has also been tested by analyzing real alloy samples.|
