摘要
以一丁基锡为模板,壳聚糖为基体,戊二醛为交联剂,制备能特异性识别MBT的分子印迹聚合物(MBT-MIPs).研究MBT-MIPs合成条件与吸附性能,并用扫描电子显微镜等技术对其进行结构表征.结果表明,与组成相似的非分子印迹聚合物相比,MBT-MIPs具有较大的吸附性能和高度的选择性及识别能力,最大吸附量为165.9μg.g-1,静态分配系数为10.66.
Monobutyltin molecularly imprinted polymers （MBT-MIPs） which have special molecule recognition ability to monobutyhin （MBT） were synthesized with MBT as template chitosan as the functional monomer and glutaraldehyde as the cross -linker In this paper, the structure of MBT-MIPs was characterized with scanning electronic microscope, and the synthesis conditions of MBT-MIPs, the adsorption properties and selective recognition of MBT-MIPs for MBT were also studied. The experimental results showed that MBT-MIPs had higher adsorption capacity and higher selective recognition for MBT compared to nonimprinted polymers （NMIPs） which had the Similar chemical composition. The maximum ad- sorption capacity of MBT-MIPs for MBT was 165.9 μg·g^-1 and the static distribution coefficient for MBT was 10.66.
