“…Therefore, the Å OH plays a vital role in the PMD degradation. The positive effects of N 2 O and O 2 on the radiolysis of the target pollutants were also reported in other studies on the radiolytic degradation of organic compounds such as chlorpyrifos [28], 4-chloraniline [37], benzene sulfonate [38], 2,4-dichlorophenoxyacetic acid [39] and 2,4, 6-trinitrotoluene [32,40]:…”
