Abstract

This review mainly focused on the synthesis and properties of triazine-based materials as well as the state-of-the-art development of these materials in adsorption-based extraction techniques in the past 5 years, such as solid-phase extraction, magnetic solid-phase extraction, solid-phase microextraction and stir bar sorptive extraction, and the detection of various pollutants, including metal ions, drugs, estrogens, nitroaromatics, pesticides, phenols, polycyclic aromatic hydrocarbons and parabens. In the triazine-functionalized composites, triazine-based polymers and covalent triazine frameworks have been developed as the adsorbents with potential for environmental pollutants, mainly relying on the large surface area and the affinity of triazinyl groups with the targets. Triazine-based adsorbents have satisfactory sensitivity and selectivity towards different types of analytes, attributed from various mechanisms including π–π, electrostatics, hydrogen bonds, and hydrophobic and hydrophilic effects. The prospects of the materials for adsorption-based extraction were also presented, which can offer an outlook for the further development and applications.

吸附剂萃取技术中三嗪类材料的最新进展

摘要

这篇综述主要集中在三嗪基材料的合成和性能以及这些材料在过去 5 年中在吸附提取技术方面的最新进展，如固相萃取、磁固相萃取等。相萃取、固相微萃取和搅拌棒吸附萃取，以及各种污染物的检测，包括金属离子、药物、雌激素、硝基芳烃、农药、酚类、多环芳烃和对羟基苯甲酸酯。在三嗪官能化复合材料中，三嗪基聚合物和共价三嗪骨架已被开发为具有环境污染物潜力的吸附剂，主要依赖于大表面积和三嗪基与目标的亲和力。三嗪基吸附剂对不同类型的分析物具有令人满意的灵敏度和选择性，这归因于各种机制，包括 π-π、静电、氢键以及疏水和亲水作用。还介绍了吸附法提取材料的前景，为进一步的发展和应用提供了展望。
