dc.description.abstract Cr(III) sorption on the strong acid exchanger Amberlyst-15(H+ ) is studied as a function of time and temperature using basic chromium sulphate [Cr4(SO4)5(OH)2] solution. Increase in temperature has a positive effect on Cr(III) sorption. The pH is observed to decrease during Cr(III) sorption with the passage of time. The film diffusion model is applied to explain the kinetic data and the exchange rate is found to be governed by the film diffusion process. From the rate constant values, the energies of activation are calculated using the Arrhenius equation. The low activation energy confirmed the diffusional nature of the sorption process. en_US
