Peroxyacetic acid has been widely used in food, medical, and synthetic chemical fields for the past several decades. Recently, peroxyacetic acid has gradually become an effective alternative disinfectant in wastewater disinfection and has strong redox capacity for removing micro-pollutants from drinking water. However, commercial peroxyacetic acid solutions are primarily multi-component mixtures of peroxyacetic acid, acetic acid, hydrogen peroxide, and water. During the process of water treatment, peroxyacetic acid and hydrogen peroxide (H₂O₂) often coexist, which limits further investigation on the properties of peroxyacetic acid. Therefore, analytical methods need to achieve a certain level of selectivity, particularly when peroxyacetic acid and hydrogen peroxide coexist. This review summarizes the measurement and detection methods of peroxyacetic acid, comparing the principle, adaptability, and relative merits of these methods.

在过去的几十年中，过氧乙酸已广泛用于食品，医学和合成化学领域。近来，过氧乙酸已逐渐成为废水消毒中的有效替代消毒剂，并且具有很强的氧化还原能力，可从饮用水中去除微量污染物。但是，市售的过氧乙酸溶液主要是过氧乙酸，乙酸，过氧化氢和水的多组分混合物。在水处理过程中，过氧乙酸和过氧化氢（H ₂ O ₂）通常并存，这限制了对过氧乙酸性质的进一步研究。因此，分析方法需要达到一定的选择性水平，特别是当过氧乙酸和过氧化氢共存时。综述了过氧乙酸的测定和检测方法，并比较了这些方法的原理，适用性和相对优点。
