Abstract

Substances that possess hierarchical and interconnected porous features are ideal choices for acting as skeletons to synthesize surface molecularly imprinted polymers (MIPs). In this work, rape pollen, a waste of biological resources, was calcined and a porous mesh material with a high specific surface area was obtained. The cellular material was adopted as a supporting skeleton to synthesize high-performance MIPs (CRPD-MIPs). The CRPD-MIPs presented an ultrathin imprinted layered structure, with an enhanced adsorption capacity for sinapic acid (154 mg g) relative to the non-imprinted polymers. The CRPD-MIPs also exhibited good selectivity (IF = 3.24) and a fast kinetic adsorption equilibrium (60 min). This method exhibited a good linear relationship (R2 = 0.9918) from 0.9440 to 29.26 μg mL, and the relative recoveries were 87.1-92.3%. The proposed CRPD-MIPs based on hierarchical and interconnected porous calcined rape pollen may be a valid program for the selective extraction of a particular ingredient from complicated actual samples.

摘要

具有分级和相互连接的多孔特征的物质是用作骨架来合成表面分子印迹聚合物（MIP）的理想选择。在这项工作中，将油菜花粉（一种生物资源废物）进行煅烧，得到了具有高比表面积的多孔网状材料。采用该细胞材料作为支撑骨架来合成高性能MIP（CRPD-MIP）。CRPD-MIP呈现出超薄的印迹层结构，相对于非印迹聚合物，对芥子酸的吸附容量增强（154 mg g）。CRPD-MIP还表现出良好的选择性（IF = 3.24）和快速的动力学吸附平衡（60分钟）。该方法在0.9440至29.26 μg mL范围内呈现出良好的线性关系（R2 = 0.9918），相对回收率为87.1-92.3%。所提出的基于分级和相互连接的多孔煅烧油菜花粉的CRPD-MIP可能是从复杂实际样品中选择性提取特定成分的有效方案。
