Pesticides are excessively used in agriculture to improve the quality of crops by eliminating the negative effects of pests. Among the different groups of pesticides, triazine pesticides are a group of compounds that contain a substituted C H N heterocyclic ring, and they are widely used. Triazine pesticides can be dangerous for humans as well as for the aquatic environment because of their high toxicity and endocrine disrupting effect. However, the concentration of these chemical compounds in water samples is low. Moreover, other compounds that may exist in the water samples can interfere with the determination of triazine pesticides. As a result, it is important to develop sample preparation methods that provide preconcentration of the target analyte and sufficient clean-up of the samples. Recently, a wide variety of novel microextraction and miniaturized extraction techniques (e.g., solid-phase microextraction and liquid-phase microextraction, stir bar sorptive extraction, fabric phase sorptive extraction, dispersive solid-phase extraction, and magnetic solid-phase extraction) have been developed. In this review, we aim to discuss the recent advances regarding the extraction of triazine pesticides from environmental water samples. Emphasis will be given to novel sample preparation methods and novel sorbents developed for sorbent-based extraction techniques.
农药在农业中被过度使用，以消除害虫的负面影响来提高作物的质量。在不同类型的农药中，三嗪类农药是一类含有取代的 C H N 杂环的化合物，它们被广泛使用。由于三嗪类农药毒性高且具有内分泌干扰作用，对人类和水生环境都可能构成危险。然而，这些化学化合物在水样中的浓度较低。此外，水样中可能存在的其他化合物可能会干扰三嗪类农药的测定。因此，开发提供目标分析物预浓缩和样品充分净化的样品制备方法非常重要。最近，已经开发出了多种新型微萃取和微型萃取技术（例如固相微萃取和液相微萃取、搅拌棒吸附萃取、纤维相吸附萃取、分散固相萃取和磁性固相萃取）。在本文中，我们旨在讨论从环境水样中萃取三嗪类农药的最新进展。重点将放在基于新型吸附剂的萃取技术的新型样品制备方法和新型吸附剂上。
