And the article contained the following:
Effluent organic matter (EfOM) contains a large number of substances that are harmful to both the environment and human health. To avoid the neg. effects of organic matter in EfOM, advanced treatment of organic matter is an urgent task. Four typical oxidants (H2O2, PS, PMS, NaClO) and UV-combined treatments were used to treat micro-contaminants in the presence or absence of EfOM, because the active radical species produced in these UV-AOPs are highly reactive with organic contaminants. However, the removal efficiency of trace contaminants was greatly affected by the presence of EfOM. The degradation kinetics of two representative micro-contaminants (benzoic acid (BA) and para chlorobenzoic acid (pCBA)) was significantly reduced in the presence of EfOM, compared to the degradation kinetics in its absence. Using the method of competitive kinetics, with BA, pCBA, and 1,4-dimethoxybenzene (DMOB) as probes, the radicals (HO路, SO4-路, ClO路) proved to be the key to reaction species in advanced oxidation processes. UV irradiation on EfOM was not primarily responsible for the degradation of micro-contaminants. The second-order rate constants of the EfOM with radicals were determined to be (5.027 卤 0.643) x 102 (SO4-路), (3.192 卤 0.153) x 104 (HO路), and 1.35 x 106 (ClO路) (mg C/L)-1 s-1. In addition, this study evaluated the production of three radicals based on the concept of Rct, which can better analyze its reaction mechanism. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).SDS of cas: 150-78-7
