“…The required dose for removal of 50% and 90% of PMD was summarized in Table 1. The results showed an electron beam radiolysis is an efficient method to degrade the refractory contaminants, agreeing with the previously reported studies [28,32,33].…”

“…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]:…”

“…For example, Wu et al [26,27] studied and found that the electron beam radiolysis was an effective method to degrade phthalate aqueous solution. Iamail et al [28] investigated the degradation of chlorpyrifos by gamma irradiation and demonstrated that the oxidative Å OH radicals are the most important species during the process. Moreover, pollutants can be degraded in most cases to less toxic and in some cases to more biodegradable compounds by ionizing irradiation.…”

In this study the radiation-induced degradation of crystal violet (CV) dye under various experimental conditions has been investigated. D 0.5 , D 0.9 and D 0.99 values suggests that lower doses are required for 50%, 90% and 99% removal of CV dye when the sample solution contains excessive amount of• OH radicals. The removal efficiency of CV dye in terms of G-values was also calculated under each reaction conditions. The results showed that• OH radicals are playing effective role in the degradation of CV dye as compared to e aq -and • H radicals. The gamma irradiation process effectively degraded CV dye at all pH values. The organic byproducts were examined and accordingly degradation pathway was proposed.

“…In a word, chlorpyrifos oxon and TCP are two primary transformation products of chlorpyrifos, which are derived from the oxidation of the P S double bond into the P O bond and hydrolysis at the P O bond adjacent to the benzene ring, respectively. Although many researches have been conducted on the degradation of chlorpyrifos by photolysis [3,20], hydrolysis [10], and microorganisms [21], most of them have focused on the transformations of chlorpyrifos in soil and water. Chlorpyrifos can exist in both gas and particle phases in the ambient atmosphere because of its semivolatile nature (1.8 × 10 −5 mm Hg at 25 • C) [22][23][24][25].…”

a b s t r a c tChlorpyrifos is a typical chlorinated organophosphorus pesticide. The heterogeneous reaction of chlorpyrifos particles with NO 3 radicals was investigated using a vacuum ultraviolet photoionization aerosol time-of-flight mass spectrometer (VUV-ATOFMS) and a real-time atmospheric gas analysis mass spectrometer. Chlorpyrifos oxon, 3,5,6-trichloro-2-pyridinol, O,O-diethyl O-hydrogen phosphorothioate, O,O-diethyl ester thiophosphoric acid, diethyl hydrogen phosphate and a phosphinyl disulfide compound were identified as the main degradation products. The heterogeneous reaction pathways were proposed and their kinetic processes were investigated via a mixed-phase relative rate method. The observed effective rate constant is 3.4 ± 0.2 × 10 −12 cm 3 molecule −1 s −1 .
