| Abstract: | Graphene oxide(GO)was prepared by the improved Hummers method,and ethylenediamine(EDA)was employed as the reducing agent to prepare three-dimensional networked graphene hydrogel.Using ultraviolet spectrophotometer to examine its performance of Pb2+adsorption,the results showed that it took around 120 minutes to reach adsorption equilibrium,and with the adsorbent dosage of 18 mg and the lead chloride solution mass fraction of 80 mg/L,the adsorption effect was the best,and its adsorption behavior conformed better to the secondary adsorption dynamics model,indicating that the Pb2+adsorption of graphene hydrogels is mainly chemical adsorption. |
