We focused on paring the adsorption properties of mesoporous silica, zeolite, diatomaceous earth for heavy metal ions, carried out the static adsorption experiments for the solution of Cu2 +、 Pb2 + and Cd2 + , initially determined the optimal conditions of mesoporous silica for different ion adsorption. Experimental results show that:The adsorption capacity of Zeolite for Cu2 +、 Pb2 + and Cd2 + are mg/g、 mg/g and mg/g, respectively。 adsorption experiments 設計（論文）專用紙 7 / 42
