纤维素基印迹吸附剂的制备及研究性能

Preparation and Properties of Cellulose-based Molecular Imprinted Adsorbent

以纤维素为原料,1-乙烯基咪唑为最佳功能单体,2,4-二氯苯酚(2,4-DCP)作为模板分子,采用分子印迹技术结合原子转移自由基聚合方法,制备纤维素基印迹吸附材料。利用红外光谱(FT-IR)及扫描电镜(SEM)对材料的结构及性能进行了表征,并对纤维素印迹吸附剂的选择性吸附性能进行研究。

Cellulose-based imprinted material was prepared by molecular imprinting technique combined atom transfer radical polymerization method using cellulose as raw materials, 1-vinyl imidazole as the functional monomer, 2,4-DCP as template molecule. The structure and properties of the adsorption were characterized by Fourier transform infrared spectoscopy（FT-IR） and scanning electron microscope （SEM） analysis. Moreover, the selective adsorption performance of the imprinted adsorbent was studied.
