“…The H-atoms can principally form also adducts or abstract CI-or H-atom from TCE-molecule. It has been reported earlier (Koltzenburg et al, 1982; see also Lal et al, 1987;Getoff, 1993a) that in general alkyl radicals with leaving groups on fl-position, resulting from the reaction of OH with a halogenated compound, undergo a fast hydrolysis. As a result of this OH-group is incorporated on the place of the Cl-atom, e.g.…”

Abstract--The radiation-induced decomposition of biological resistant pollutants in drinking as well as in wastewater is briefly reviewed. First, some important units, definitions etc., radiation sources, as well as dose-depth curves in water as functions of the electron energy and 6°Co-y-rays are mentioned. Following is a schematical presentation of water radiolysis and of characteristics of primary free radicals. Then the degradation of some aliphatic and aromatic chlorinated compounds in the presence of air is presented. Some spectroscopic and kinetic data of transients resulting from chlorinated phenols are also quoted in order to illustrate and to explain the rather complicated degradation mechanisms. In this respect the synergistic effect of radiation and oxygen as well as that of ozone is also discussed. Finally, a scheme for technical application of high energy elelctron beam is presented.

“…Hence, the attacking.species under these conditions are OH as well as HO2/O i which are leading to the corresponding TCE-adducts. They are unstable and can undergo a multiple hydrolysis (Koltzenburg et al, 1982;Lal et al, 1987;Getoff, 1993a) e.g.…”

“…This may be due to the consumption of SCI by some species (in addition to Cl-RO 2 ) formed uniquely in the presence of chlorocyclohexane, which suppresses the growth of the oligomer chain. It has been reported that the oxidation of chloroalkanes forms HCl, 64,65 and it is likely that HCl is also produced in the OH initiated oxidation of chlorocyclohexane. If HCl reacts with SCI, as discussed below, it will inhibit the formation of longer oligomers.…”

“…This isomerization presumably occurs after formation of a single-bonded intermediate, which might be the radical cation formed by electron-transfer to sulfate radical (Minisci, Citterio, & Giordano, 1983), or the sulfate radical radical adduct, formed by asymmetric addition of sulfate radical to the double bond. Evidence for the latter is strong, with many sulfate radical adducts with alkenes having been identified by electron spin resonance (Chawla & Fessenden, 1975) (Davies & Gilbert, 1984;Koltzenburg, Behrens, & Schulte-Frohlinde, 1982). It is less clear, however, what factors control the elimination of sulfate radical to form the isomerized DCE's.…”
