摘要:

采用分子印迹技术,以三七素的结构类似物甘氨酸DL亮氨酸(GL)为假模板分子、二甲亚砜(DMSO)为致孔剂,优化合成条件制备了对三七素有较好选择识别性的假模板分子印迹聚合物(DMIPs)。等温吸附实验证明,与空白印迹聚合物(NIPs)相比,DMIPs对三七素的吸附效果更佳,具有更高的吸附容量。吸附动力学实验中,DMIPs能快速吸附三七素,15 min即能达到最大吸附量的916%。选择性实验中,DMIPs对三七素不同的结构类似物有良好的选择识别性,而NIPs则无此特性。研究结果表明,该分子印迹聚合物有作为高选择性材料在水溶液环境中选择性分离富集三七素的潜能。

Abstract:

We employed molecularly imprinted technology to prepare dummy molecularly imprinted polymers (DMIPs) with high selectivity and affinity to dencichine with glycylDLleucine (GL) as a dummy template and DMSO as porefoaming agent. Absorption isotherm experiment show that DMIPs have higher absorption capability to dencichine, as compared with nonimprinted polymers (NIPs). In absorption kinetics experiment, DMIPs can rapidly absorb dencichine,attaining 91.6% of the maximum absorbing capacity with only 15 minutes. In selection experiment, DMIPs have better selective recognition capability to different analogues of dencichine, but NIPs do not have. This shows that DMIPs have extraction and separation potency to dencichine from aqueous solution as highly selective material.

Key words: molecularly imprinted polymers, dencichine, recognition property
