摘要
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 ofperoxyacetic 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.
