| Abstract: | Objective] To study the effect of chitosan and Fe3O4 magnetic modified chitosan on the adsorptive performance of Pb2+.Method] The impact of non-modified chitosan dose and adsorption time as well as the adsorptive pH and temperature of magnetic modified chitosan on the removal of Pb2+ in wastewater was studied.Result] Under 80 min of adsorption time,4.5 of pH and 298 K of temperature,the removal rate of Pb2+ in wastewater could be up to 99.5%.Conclusion] The Pb2+ adsorptive capacity of magnetic modified chitosan was greatly enhanced,the removal rate was improved,and the environmental pollution by wastewater was reduced. |
