摘　　要：利用γ-氨基丙基-三乙氧基硅烷偶联剂与活化硅胶表面的羟基反应,制备了硅烷化硅胶,所得产物与壳聚糖反应合成了硅胶/壳聚糖复合吸附材料。通过红外光谱分析(IR),扫描电镜(SEM)及能谱分析对复合材料进行表征,并测试了硅胶/壳聚糖复合材料对Zn2+、Cd2+的吸附能力。结果表明:复合吸附材料对Zn2+、Cd2+具有很好的吸附能力,最大吸附率为96.01%及90.65%。The reaction of γ-aminopropyl-triethoxysilane coupling agent and the activation silica gel surface＇s hydroxide radical is utilized to prepare silanization silane gel, which the product and chitosan react to compound the composite adsorption material of silane gel/chitosan. The composite material is characterized by infrared spectral analysis （IR）, scan the electric mirror （SEM） and the energy spectrum analysis, and the adsorption ability of composite adsorption material of silane gel/chitosan to Zn^2＋ and Cd^2＋ is tested. The result shows that the composite adsorption material has good adsorption ability to Zn^2＋ and Cd^2＋ , and the maximal adsorption rate is 96.01% and 90.65%.
