Abstract
A kinetic study was done of the dechlorination of polychlorinated biphenyls (PCBs) eliminated from contaminated dielectric oils by using the potassium poly(ethylene glycolate) (KPEG) process. Experimental runs at laboratory s cale showed that the kinetics of the removal reaction was first-order for e ach PCB present and first-order with respect to the KPEG concentration. The PCB elimination grade was also affected by the KOH/PEG ratio. An exponenti al correlation was found between the kinetic constant for each congener and its respective gas chromatographic relative retention time.
