      This work studied the improvement of adsorption properties of chitosan by crosslinking. The crosslinked chitosan was used as an adsorbent for removal of chromium from wastewater. Sodium tripolyphosphate was used as crosslinking agent. The FTIR spectrum showed the existing of amino and phosphate groups, indicated to the crosslinking between chitosan chains. The adsorption of chromium over the crosslinked chitosan bead was carried out in batch experiment. The effect of operating parameter on the adsorption efficiency such as pH of tripolyphosphate solution, initial concentration, pH and temperature of chromium solution and amount of adsorbent loading were investigated. The results showed that the removal of chromium increased continuously within the first 60 minutes, then slowly increased until reached the equilibrium in 120 min for all experimental conditions. The pH of the sodium tripolyphosphate solution suitable for the synthesis of absorbent material was 10. The pH of chromium solution had a strong effect on the removal of chromium. The maximum chromium removal was obtained at pH 2. The removal of chromium on the crosslinked chitosan was insignificantly affected by the temperature of chromium solution in the range of experimental temperature. The chromium removal increased with the adsorbent loading, the highest removal was 92.42% at 2.0 g. Additionally, the adsorption behaviour of chromium on the crosslinked chitosan corresponded with the Langmuir model, indicating the single layer adsorption. This study showed that the using of crosslinked chitosan bead has the ability to removal of chromium within the legal limit, high durability and can be separated from the wastewater after the treatment.
