|Title:||Synthesis and application of cross-linked graft copolymer from poly(vinyl alcohol) and malic acid|
|Keywords:||Analytical chemistry;Cross-linked copolymers;Polymers;Graft copolymers;Solid phase extraction;Lead|
|Abstract:||A novel polymeric sorbent has been synthesized by graft copolymerization of crosslinked polyvinyl alcohol with malic acid, and characterized by FTIR, TGA and swelling studies. A suitable and interesting method has been developed for the extraction and separation of lead ion with the graft copolymer. The lead ion uptake capacity of the polymer has been evaluated vis-a-vis varying pH and metal ion concentration. Pb(II) ion has been isolated quantitatively from various synthetic mixture containing metal ions (Cd(II), Zn(II), Ni(II), Hg(II)) commonly found in battery and electroplating waste. The synthesized material has also been tested for analyzing real samples such as solder, lead concentrate and electroplating waste.|
