dc.description.abstractThis work investigates the removal of chromium (VI) from aqueous solution using solvent impregnated resins (SIR). SIR have been formed by impregnating Amberlite XAD-7 with Aliquat 336 as the extractant and acetone as the solvent by a wet impregnation technique. SIR of three different concentrations, 0.5, 1.0 and 2.0 g Aliquat 336/g Amberlite XAD-7 have been prepared in two different size ranges: 300-401 and 553-711 mum. The speciation diagram of Cr(VI) in aqueous solution has been produced. The effect of pH on the sorption of chromium (VI) ions has been investigated; equilibrium experiments have been carried out with three different types of SIR to quantify the sorption capacity. The Langmuir adsorption isotherm gave a satisfactory fit of the equilibrium data. Kinetic experiments have been performed with different concentrations of SIR and different size ranges to assess the performance of the SIR and to investigate potential kinetic models for the sorption process. Vermeulen's approximation for particle diffusion has been fitted to the kinetic data and it showed very good correlation. The mechanism of chromium (VI) removal from aqueous solution by SIR has been proposed. (C) 2004 Elsevier B.V. All rights reserved.en_US
