Abstract

In this study starch/CeO₂ nano-composite was synthesised using the sol-gel method. The aim was to use the nano-composites for the removal of Cr(VI) from aqueous solution. The adsorbent was characterised using FTIR, TGA, BET analyses. The effects of dosage, initial concentration, pH, contact time and temperature were thoroughly investigated. The results showed that the optimum pH for Cr(VI) removal was pH 2 and the removal of Cr(VI) was increased with increasing dosage, smaller initial concentrations, longer contact times and higher temperatures. The data indicated that the adsorption process was a chemisorption process and the reaction was endothermic.
