In this study, the sorptive removal of hexavalent chromium from aqueous solutions by Mg-Al-CO3 hydrotalcite was investigated in a batch mode. The influence of solution pH, conditioning duration, initial chromium concentration, sorbent concentration, sorbent particle size, and temperature was tested at sorption kinetic runs. The influence of eluant concentration and volume was tested at desorption kinetic runs. Desorption experiments showed that the loaded material can be fully regenerated and reused. Four kinetic models have been evaluated if they fit the experimental data: the pseudo-first-order, a modified second-order, and two ion-exchange models. It showed that the second-order model could best describe the sorption and desorption kinetics. The Freundlich isotherm was used to fit equilibrium experiments. Hydrotalcite presented a sorption capacity of similar to17 mg Cr/g under the studied conditions. The calculated activation energy for the studied process was 24 +/- 2 kJ/mol.
