چکیده انگلیسی
A novel, bio-based Zr(IV) impregnated dithiocarbamate modified chitosan beads (Zr-DMCB) was successfully synthesized for the adsorption of Fâ from aqueous solutions. Batch adsorption experiments were performed to evaluate the adsorption conditions, selectivity and reusability. The results showed that the saturation adsorption capacity was 4.58 mg/g at pH 7.0, 30 °C for 40 min. The adsorption kinetic data was fitted with pseudo-second-order model. Adsorption process could be well described by Langmuir isotherm model and the maximum adsorption capacity calculated from Langmuir isotherm equation was 7.78 mg/g. The adsorption capacity of Zr-DMCB for Fâ was significantly affected by co-anions. The adsorption mechanism of Zr-DMCB for Fâ was characterized by FTIR, SEM and EDX analysis. The results above indicated that Zr-DMCB is a very promising biosorbent for the removal of Fâ from aqueous solutions.
