Ion Exchange Resin on Treatment of Copper and Nickel Wastewater

[摘要] On the conditions of static and dynamic ion exchange, the removal effect of Cu2+ and Ni2+ by D001 resin was investigated. Besides, the thermodynamic and kinetic characteristics in the process of adsorption were studied. The results showed that when the initial concentrations of Cu2+ and Ni2+ in the copper and nickel wastewater were 100mg/L, the temperature was 25°C and pH was 5, the removal rate at the state of equilibrium were 99.14% and 99.33% respectively. In the dynamic ion exchange experiment, when the influent flow rate was 10L/h, the exchange capacity of the resin was 13829.79mg/L for Cu2+ and 22656.70mg/L for Ni2+ at the time of breakthrough.
