| 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. |
