摘要
Abstract
This study explores the adsorption mechanism and application potential of two-dimensional nanomaterials in the removal of heavy metal wastewater.Two-dimensional nanomaterials such as graphene,MoS2 and WS2 were prepared by liquid phase stripping and a simulated heavy metal wastewater system was constructed to study the adsorption behaviour of three materials on Pb2+,Cd2+and Hg2+heavy metal ions.Langmuir and Freundlich isotherm models and quasi-second-order kinetic models were used for data fitting,and the adsorption mechanism was analyzed by Fourier Transform Infrared Spectroscopy(FTIR)and X-ray Photoelectron Spectroscopy(XPS)characterization.The results show that the two-dimensional nanomaterials exhibit high adsorption capacity,and the selective adsorption effect of heavy metal ions is more significant at low pH.关键词
