【 摘 要 】

In this study, several different kinds of organic functionalized porous silica nanomaterials were firstly synthesized via soft template method, separately. And then, the adsorption for Cd (II) ions of organic functionalized porous silica nanomaterials has been studied. Besides, the effect of the adsorption time and Cd (II) ions concentration on the absorption efficiency has also been investigated. The results showed that the adsorption had already been completed within 30 min. In addition, the equilibrium adsorption concentration of vinyl functionalized porous silica sorbents, or ureido functionalized porous silica sorbents for Cd (II) was about 150 mg/L.
