Electron beam degradation of polychlorinated biphenyls

Radiation dechlorination of some chlorinated hydrocarbons particularly of carbon tetrachloride in presence of HCO3−- or NO3−-ions

“…2aB and bB). This difference is, obviously, due to the creation of various byproducts in the course of partial dechlorination analogously as it was found with the radiation dechlorination of chloroform [62], PCE [75], PCBs [51] or by catalytic dechlorination of carbon tetrachloride over the Pt-or Pd-supported catalysts [2,4,6].…”

“…Even if many of modifiers or scavengers exhibited an evident effect in radiation dechlorination none of them led to the radiation yields approaching to high values indicating a chain dechlorination reaction. Such high values were found [22,39,40,46,52,56] in the alkaline 2-propanol solutions only. Therefore, further investigations of radiation dechlorination are needed for introducing them into the industrial exploitation.…”

“…dichlorobenzenes [15][16][17][18][19][20][21][22], chlorophenols [22][23][24][25][26][27][28][29][30], chloroanilines [31,32], chlorinated benzaldehydes [33], pesticides [34], or herbicides [35], dioxin contained soils [36,37] or incinerator offgas [38] and, last but not least, polychlorinated biphenyls (PCBs) [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56]) and aliphatic (e.g. halomethanes [21,[57][58][59][60][61][62], haloethanes …”

“…halomethanes [21,[57][58][59][60][61][62], haloethanes [18,21,22,63], chloroethenes [21,51,[60][61][62][64][65][66][67][68][69][70][71][72][73][74][75][76]) chlorinated hydrocarbons, or to their mixtures [20,[77][78][79][80][81][82][83][84][85][86][87]. Some radiation dechlorinations of actual mixture of various chlorinated hydrocarbons were successfully performed using pilot plants [51,52,81,85,87,88]. In most of them the G-values reached the units only.…”
