| Abstract |
| Adsorption is considered one of the important methods for disposing of many kinds of pollutants. In this study, a new biosorbent based on an amino acid-modified chitosan hydrogel has been successfully synthesized and characterized. Hydrogels, as a new type of biomaterial with unique physical and chemical characteristics, have three-dimensional solid networks constructed by hydrophilic polymer chains. The superior swell-ability, biocompatibility, and functionalization have made them widely explored and applied in the removal of heavy metals from waterThe capability of new chitosan hydrogel in the adsorptive removal of Pb(II) from wastewater was investigated using the Bach experiment. The influences of solution( pH, contact time, dose, time, temperature, concentration) for the performance of the new biosorbents were inspected. The maximum Pb(II) adsorption capacity by the new hydrogel was achieved with a biosorbents dose, 0.4 g; pH, 4; contact time, 5 min; and temperature 45 °C. Different strategies have been proposed for Pb(II) ion removal from water, amongst them, adsorption is extensively used due to its low process cost, high removal effectiveness and ease of process.4 |
