Ozonation is universally used during water treatment but can form hazardous brominated disinfection byproducts (Br-DBPs). While sunlight exposure advised to reduce the risk of Br-DBPs, their phototransformation pathways remain insufficiently understood. Here, irradiation was found adsorbable organic bromine by 63%. Applying high-resolution mass spectrometry, study investigated transformations dissolved matter in sunlit-ozonated reclaimed water, revealing number and abundance assigned...
The ammonia/chlorine oxidation process can greatly degrade PPCPs in water. However, its effect on molecular transformations of natural organic matter (NOM) and effluent (EfOM) are still poorly understood. In this study, NOM EfOM occurring during were explored compared with those occurred chlorination, using spectroscopy mass spectrometry. Phenolic highly unsaturated aliphatic compounds together found to be predominant both samples, all which significantly degraded after two processes. led...
During chlorination of reclaimed water, the dose chlorine used can influence formation chlorinated disinfection by-products (Cl-DBPs). We non-targeted screening by Orbitrap mass spectrometry to identify Cl-DBPs in samples and found that was likely form slightly oxidized unsaturated aliphatic compounds polycyclic aromatic compounds. Increasing increased proportion containing one atom (Cl 1 -DBPs) highly two atoms 2 -DBPs). In addition, increasing first decreased then Cl -DBPs with index...
