Abstract

Ion chromatography (IC) is a variant of high-performance liquid chromatography. Its most important applications include the determination of inorganic and some organic ions in different types of liquid samples. The development of new types of stationary phases with various separation mechanisms, sample preparation methods, and detection modes has extended ion chromatography applications to practically all ionic and ionogenic substances, as well as extending sample types to include gaseous and solid matrices. Carboxylic acids and their derivatives are examples of compounds that are becoming more frequently analyzed using ion chromatography and related techniques. Their occurrence in the environment can be natural or anthropogenic in origin and are broadly used in various industries and daily life. This article discusses the applications of ion chromatography and related techniques for the determination of carboxylic acids in different types of liquid, solid, and gaseous matrices. It also presents detailed methodologies and literature data on this subject from the last 15 years.

摘要

离子色谱 (IC) 是高效液相色谱的一种变体。其最重要的应用包括测定不同类型液体样品中的无机离子和一些有机离子。具有各种分离机制、样品制备方法和检测模式的新型固定相的开发已将离子色谱应用扩展到几乎所有离子和离子源物质，并将样品类型扩展到包括气体和固体基质。羧酸及其衍生物是越来越多地使用离子色谱和相关技术进行分析的化合物的例子。它们在环境中的出现可以是自然的，也可以是人为的，广泛应用于各个行业和日常生活中。本文讨论了离子色谱法和相关技术在测定不同类型液体、固体和气体基质中羧酸的应用。它还提供了过去 15 年关于该主题的详细方法和文献数据。
