| Abstract: | The adsorption and release characteristics of copper on Yaogongdu sediments in Poyang lake are studied. Isothermal adsorption shows that adsorption of copper on Poyang lake sediments accords with the Langmuir and Freundlich model, solUtion adsorption tends to reach a dynamic equilibrium in two hours; In addition, the release of copper hasquick and slow reaction phase, the best release time is three hours. The factors affecting adsorption and release are studied, pH is the remarkable one. |
