Abstract
Periodate-based advanced oxidation processes (IO4–-based AOPs) have attracted significant interest for degrading organic micropollutants due to their high efficiency and ease of use. However, the formation risk of iodinated disinfection byproducts (I-DBPs) during these processes has long been overlooked. At pH = 3.0–9.0, I-DBPs including iodophenols and triiodomethane were formed in the ultraviolet (UV)/IO4–/phenol system, and the total iodine concentration in I-DBPs ranged from 4.8 to 451.3 nM. In this system, the conversion of IO4– to hypoiodous acid (HOI) proceeded in two stages: (1) a rapid HOI generation phase, where IO4– first transformed into an iodine-containing intermediate followed by its subsequent…
