Polar benzotriazoles are corrosion inhibitors with widespread use; they are environmentally characterized as emerging pollutants in the water system, where they are present in low concentrations. Various extraction methods have been used for their separation from various matrices, ranging from classical liquid⁻liquid extractions to various microextraction techniques, but the most frequently applied extraction technique remains the solid-phase extraction (SPE), which is the focus of this review. We present an overview of the methods, developed in the last decade, applied for the determination of benzotriazoles in aqueous and solid environmental samples. Several other matrices, such as human urine and plant material, are also considered in the text. The methods are reviewed according to the determined compounds, sample matrices, cartridges and eluents used, extraction recoveries and the achieved limits of quantification. A critical evaluation of the advantages and drawbacks of the published methods is given.
极性苯并三唑是一种用途广泛的腐蚀抑制剂；它们在环境中被视为水系中的新兴污染物，其浓度较低。已经使用了各种萃取方法将其从各种基质中分离出来，从经典的液-液萃取到各种微萃取技术，但最常应用的萃取技术仍然是固相萃取（SPE），这也是本综述的重点。我们概述了过去十年中开发的方法，这些方法用于测定水相和固相环境样品中的苯并三唑。文本中还考虑了其他几种基质，如人尿和植物材料。根据所测定的化合物、样品基质、使用的萃取小柱和洗脱液、萃取回收率以及实现的定量限对方法进行了回顾。对已发表方法的优缺点进行了批判性评估。
