This review approaches how aqueous two-phase systems (ATPS), in their various compositions (e.g., polymer + salt, copolymer + salt, ionic liquid + salt, acetonitrile + salt), can be efficiently used for extraction, preconcentration, and clean-up of analytes in aqueous samples to determine the compounds classified as emerging contaminants (ECs). In the literature, there are some studies using ATPS applied to ECs, like pesticides, pharmaceuticals, illicit drugs, personal care products, alkaloids, and hormones, even when in trace concentrations. The ATPS is an alternative to the conventional liquid-liquid extraction technique. However, it is predominantly composed of water and do not generally use organic solvents and, therefore, is based on the principles of green chemistry. An ATPS approach has a unique advantage because it can extract neutral, anionic, cationic, polar, and nonpolar compounds, even when present simultaneously in the same sample. This review covers how this simple and low environmental impact technique has been employed for the analysis of different classes of emerging contaminants.

这篇综述探讨了如何在其各种成分（例如聚合物+盐，共聚物+盐，离子液体+盐，乙腈+盐）中有效地使用水两相系统（ATPS）进行萃取，预浓缩和清洁，对水性样品中的分析物进行分析，以确定归类为新兴污染物（EC）的化合物。在文献中，有一些使用ATPS应用于EC的研究，即使是微量的农药，如农药，药物，非法药物，个人护理产品，生物碱和激素。ATPS是常规液-液萃取技术的替代方法。但是，它主要由水组成，通常不使用有机溶剂，因此是基于绿色化学原理的。ATPS方法具有独特的优势，因为它可以提取中性，阴离子，阳离子，极性和非极性化合物，即使同时存在于同一样品中也是如此。这篇综述涵盖了如何使用这种简单且对环境影响小的技术来分析不同类别的新兴污染物。
