摘要

由于环境样品中可能存在的硝基苯残留会造成潜在的危害，因此开发有效的分析方法对某些环境样品中硝基苯的定量分析是监测环境质量和保护公众健康的必要条件。在此，我们通过Friedel-Crafts烷基化，绿色合成天然葛根素基超交联聚合物（Pue-HCP1），开发了一种天然产物衍生的固相微萃取（SPME）涂层。pue - hcp1基纤维涂层具有丰富的吸附位点和适宜的疏水性，对NBs的富集系数高达1112-6483。该涂层还表现出良好的稳定性和耐久性。将SPME与气相色谱-火焰电离检测相结合，建立了一种灵敏可靠的环境水和土壤样品中NBs检测方法，灵敏度高(水的检出限为0.01 ~ 0.2 ng mL-1；土壤为0.4 ~ 1.0 ng g-1)，精密度高，回收率为83.8% ~ 115%。

Construction of a natural puerarin-based green hypercrosslinked polymer fiber coating for the effective SPME of nitrobenzenes from environmental samples

Due to the potential hazardous effect caused by the possible nitrobenzenes (NBs) residues in environmental samples, the development of effective analytical methods for the quantification of NBs in some environmental samples becomes necessary in monitoring the environmental quality and protecting the public health. Herein, we developed a natural product-derived solid-phase microextraction (SPME) coating through a green synthesis of a natural puerarin-based hypercrosslinked polymer (Pue-HCP1) via Friedel-Crafts alkylation. Featuring abundant adsorption sites and suitable hydrophobicity, the Pue-HCP1-based fiber coating achieved the enrichment factors as high as 1112–6483 for the NBs. The coating also exhibited a good stability and durability. By integrating the SPME with gas chromatography-flame ionization detection, we developed a sensitive and reliable method for detecting NBs from environmental water and soil samples, with high sensitivity (limits of detection: 0.01–0.2 ng mL^-1 for water; 0.4–1.0 ng g^-1 for soil) and good accuracy (recoveries: 83.8%-115%).

期刊介绍： The Journal of Chromatography A provides a forum for the publication of original research and critical reviews on all aspects of fundamental and applied separation science. The scope of the journal includes chromatography and related techniques, electromigration techniques (e.g. electrophoresis, electrochromatography), hyphenated and other multi-dimensional techniques, sample preparation, and detection methods such as mass spectrometry. Contributions consist mainly of research papers dealing with the theory of separation methods, instrumental developments and analytical and preparative applications of general interest.
