OH and SO4− radicals accounted for 4.6% and 52.7%, respectively, of DDBAC degradation. The calculated kOH,DDBAC and kSO4-,DDBAC rate constants were (1.45 ± 0.16) × 109 and (1.51 ± 0.02) × 109 M−1 s−1, respectively. The kobs rate constant for DDBAC degradation increased from 0.047 to 0.150 min−1 when the PS dose was increased from 0.05 to 1.45 mM. The presence of natural organic matter (NOM), HCO3−...
Benzalkonium chlorides (BACs), as typical cationic surfactants and biocides widely applied in household and industrial products, have been frequently detected as micropollutants in many aquatic environments. In this study, the combination of UV irradiation and chlorine (UV/chlorine), a newly interested advanced oxidation process, was used to degrade dodecylbenzyldimethylammonium chloride (DDBAC)....
