| Abstract: | The ion exchange of Cd2 into synthesized analcime (ANA) were studied. The effects of such factors on the cadmium exchange amount as pH value,temperature,initial Cd2 concentration and other cations coexist in solution were investigated separately. The removal efficiency of Cd2 in simulate wastewater was also characterized. The result shows that the removal efficiency of Cd2 could achieve over 99.0%. |
