【Abstract】 The adsorption equilibrium and kinetics data of copper ion on 5A molecular sieves were measured.The adsorption equilibrium data were simulated with Langmuir adsorption model.The adsorption equilibrium data were in conformity with the calculating value with the model parameter.Results has showed that Langmuir adsorption model is suitable for describing characteristics of the system including copper ion and SA.The adsorption mechanism obtained by XRD methods is a synthetical action of physicsal and chemical actions.Adsorption effect is promoted by Chemical action.Those data are necessary for the design of the adsorption separation process and provide a basis for concurrent treatment of wastwaters containing copper ion and nitrate radical.更多还原
