摘要:以氯化鎘為模板分子，殼聚糖為功能單體，γ-(2,3環氧丙氧)丙基三甲氧基硅烷（KH-560）作為交聯劑同時加入一定量的活化硅膠利用表面分子印跡技術和溶膠-凝膠法制備了鎘離子印跡聚合物。

　　　在制作過程中進行條件優化，通過對實驗中單因素：模板分子與交聯劑不同摩爾比，交聯反應時間，殼聚糖的用量，凝膠干燥溫度的的研究。確定鎘離子印跡聚合物的最佳制作方法：模板分子與交聯劑的摩爾比為1:16，交聯反應時間為4h,殼聚糖的用量為1g，凝膠干燥溫度為25℃，并采用0.5mol/L的鹽酸在超聲的條件下進行洗脫，并用原子吸收分光光度法測量洗脫后的樣品的吸光度，此結果是通過正交試驗后得出的吸附性能最佳的聚合物樣品。以此方法制作出的樣品的最大飽和吸附量為31.75mg/g。

Abstract:as a template molecule, Chitosan as a functional monomer, 3-methoxy glycidyl ether epoxy propyl KH-560 silane as crosslinker while adding a certain amount of activated silica gel using surface Molecular Imprinting technology and preparation of cadmium ion imprinted sol-gel polymer.

　　　Optimization in the production process conditions, by means of single factor experiments into: template molecules with different mole ratio of cross-Linking agent, crosslinking reaction time, dosage of chitosan, the gel drying temperature. To determine the cadmium ion imprinting polymer in the best production method ：Template molecular and the molar ratio of cross-Linking agent as 1:16, crosslinking reaction time is 4 h, the dosage of the chitosan is 1 g, geL drying temperature is 25 ℃, and use the 0.5 mol/L HCL in ultrasound under the conditions of elution, and atomic absorption spectrophotometry measuring the absorbance of samples after elution, this result is through the orthogonal test optimum polymer adsorption performance of the samples. Method to produce the sample of the Largest saturated adsorption capacity of 31.75 mg/g.
