What is Chlorinated hydrocarbons and PAH decomposition in dry and humid air by electron beam irradiation about?

The mechanism and kinetics of CCl 4 ; CH 2 Cl 2 ; C 2 HCl 3 ; C 2 H 2 Cl 2 ; C 2 H 5 Cl and polycyclic aromatic hydrocarbons (PAH), e.g. naphthalene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene and benzo(a)pyrene, decomposition have been investigated in dry and humid air under the influence of electron beam irradiation, by computer simulation based on established theoretical models. The experimental data published in the literature and the results of calculations confirmed an assumption that thermalized electron dissociative attachment reactions are an important part of the chlorinated VOCs decomposition process. The exception is CH 2 Cl 2 where the decomposition process is initiated by nitrogen atoms and N 2 + ions. A chain reaction was observed in the case of C 2 HCl 3 and C 2 H 2 Cl 2 decomposition, where the dose necessary for 90% reduction is below 10 kGy. In contrast to the chlorinated VOC's, PAHs in humid air were primarily decomposed by OH radical's interactions. When initial PAH concentration was p100 ppm the dose necessary for 90% reduction was below 10 kGy.
