When determining contaminants from environmental samples, sample treatment plays an important role. Among the different extraction techniques available, solid-phase extraction (SPE) has been commonly used for liquid samples, as well as for solid samples after an extraction technique amenable for solids. The broad applicability of SPE is attributed to the availability of different sorbents. Among these sorbents, the mixed-mode ion-exchange polymeric ones have been widely exploited since they suitably combine both capacity (to concentrate the compounds) and selectivity (to clean-up the interferences from complex matrices). This review overviews the application of mixed-mode ion-exchange polymeric sorbents in environmental field when water and solid samples are analyzed. The sample analyzed, the compounds determined, the type of mixed-mode sorbent selected, the approach used and the SPE protocol applied are comprehensively discussed through different examples. This review intends to summarize the role of mixed-mode ion-exchange polymeric sorbents in the environmental field.
在确定环境样品中的污染物时，样品处理起着重要作用。在可用的不同提取技术中，固相萃取 (SPE) 已广泛用于液体样品，以及经过适用于固体的提取技术处理的固体样品。SPE 的广泛适用性归因于不同吸附剂的可用性。在这些吸附剂中，混合模式离子交换聚合物吸附剂得到了广泛的应用，因为它们既能有效地浓缩化合物，又能有效地清除复杂基质中的干扰物。本综述综述了混合模式离子交换聚合物吸附剂在分析水和固体样品时在环境领域的应用。通过不同的实例，全面讨论了分析的样品、测定的化合物、选择的混合模式吸附剂类型、使用的方法和应用的 SPE 方案。本综述旨在总结混合模式离子交换聚合物吸附剂在环境领域中的作用。
