Advance on the sample preparation and analytical methods for water disinfection byproducts

Exposure to trace levels of toxic disinfection byproducts (DBPs) can pose significant environmental security risks and adversely impact human health. Recent advancements in efficient sample preparation and sensitive analytical methods have significantly supported the high-throughput identification, accurate determination, and rapid sensing of water DBPs. These advancements facilitate studies on formation mechanism study, toxicity evaluation, and risk management of DBPs. In this paper we systematically reviewed the advance on the sample preparation and analytical methods for analyzing trace and diverse DBPs across various aquatic environments. Efficient sample preparation methods introduced for DBPs analysis significantly enhance the separation and preconcentration efficiency, thereby improving the analytical sensitivity and accuracy when coupled with adaptable analytical techniques. Moreover, we summarized the application of these methods in monitoring water quality, investigating DBPs formation mechanism and evaluating DBPs removal efficiency. Finally, the challenges and future perspectives were discussed to provide readers with insightful trends in the field.
