Abstract

The increasing demand for low-cost adsorbents used in environmental protection processes and especially for water treatment processes has given rise to low-cost alternative adsorbents. Application of chitinous products as alternative adsorbents in water treatment has received considerable attention in recent years. Chitosan obtained from shrimp waste gives very good adsorbent proprieties with low cost. In the present work, the ability of chitosan as an adsorbent for humic acid in the form of sodium humate in aqueous solution was studied. For this batch adsorption tests were carried out at ambient temperature. The results of the adsorption kinetics showed very rapid adsorption of humic acid within a period of time which does not exceed 30 minutes with high removal that is 65%.
