Abstract: | A novel graft copolymer of 2-(methacryloyloxy)ethyl] trimethylammonium chloride onto poly(vinyl alcohol) has been synthesized
and it is cross-linked by glutaraldehyde for the investigation of its efficiency in removing Cr(VI) from aqueous solution.
The chemical nature of the ion-exchange resin has been elucidated with the help of chemical test, Fourier transform infrared,
thermo gravimetric analysis and DTA. Particle size, surface area, ion-exchange capacity, optimum pH, reaction time and temperature
for Cr(VI) extraction were determined. Chromium(VI) adsorption kinetics, isotherm and thermodynamics have been studied. A
plausible mechanism for chromium ion-exchange has been suggested. |
