Abstract:To study the adsorption effect of zeolite powder on heavy metal copper, the indoor test is carried out. And the natural zeolite powder, 4-A zeolite powder and modified zeolite powder based on the natural zeolite powder made by the high temperature roasting with fly ash as adsorbent are selected for static adsorption of heavy metal Cu2+. In order to verify the ability of adsorption removal of Cu2+, cement is added as adsorbent. The static adsorption experiment shows that the adsorption capability for the Cu2+ is as follows:4-A zeolite powder ≈ modified zeolite powder > natural zeolite powder > > cement. Considering the economic factors and preparation technology, the modified zeolite powder is the best choice to removing Cu2+. The optimum content of modified zeolite powder removal Cu2+ is:2 g:100 mg/L. The pH between 5-8 is better for the adsorption.
