微孔有机网络复合材料的制备及其固相萃取持久性有毒污染物应用

This project focusses on the fabrication of novel microporous-organic network composites for solid phase extraction of trace persistent toxic substances (PTS) such as polychlorinated biphenyls, polycyclic aromatic hydrocarbons, octyl phenol and nonyl phenol. The aim of this project is to fabricate the novel MONs composites with good solvent and mechanical stability and morphology, to investigate the effects of the composition and structure of MONs composites on the extraction selectivity and efficiency, and to develop novel methodology for magnetic and on-line solid phase extraction of trace PTS on the MONs composites. This project is of great importance for monitoring trace PTS in environment and reducing the damage to environment and human from the PTS.

本项目旨在研究以微孔有机网络（MONs）复合材料为新颖吸附剂的固相萃取持久性有毒污染物（PTS）新方法。拟制备兼具基质材料良好稳定性和形貌和MONs优良吸附性能的MONs复合材料，以多氯联苯、多环芳烃、辛基酚和壬基酚等重要PTS为分析对象，探讨MONs复合材料的组成和结构与固相萃取选择性和富集效率之间的关系，发展基于MONs复合材料的磁固相萃取和在线固相萃取新方法，为进一步控制和削减PTS对环境和人类的危害提供高效的分离分析新方法。

本项目紧密围绕微孔有机网络（MONs）及其复合材料的制备、功能化及其固相萃取和色谱分离持久性有毒污染物应用开展研究，建立了多种制备MONs及其复合材料新颖吸附剂和色谱固定相的新策略，发展了系列基于MONs及其复合材料的固相萃取、污染物去除和色谱分离新方法。以通讯作者在本领域主流期刊上发表相关论文30余篇（包括Chem. Eng. J., J. Mater. Chem. A, J. Hazard. Mater., Trends Anal. Chem., ACS Appl. Mater. Interfaces, J. Chromatogr. A, 和Talanta等），完成了预定的研究目标。
