| الوصف: | Batch experiments were performed to investigate the removal of Cu2+ , Cl- , and 2,4-dichlorophe- noxyacetic acid (2,4-D) from aqueous solution using chitosan-modified bentonite. When the chi-tosan was loaded on the bentonite, the inter-layer space of the montmorillonite increased and the adsorption efficiency enhanced, as chitosan contains large numbers of -NH2 and -OH functional groups that could serve as coordination sites to bind heavy metals. In this study, the bentonite that was prepared through three procedures: Na2CO3 treatment, thermal treatment and compound treatment, was modified by chitosan. Experimental results demonstrated that the average removal rates of Cu2+ , Cl-, and 2,4-D effectively were 94.87 %, 86.19 % and 91.06 %, respectively. |
