abstract
In this paper are presented the obtained results in the development and partial validation of an analytical method for determination of PCBs present in transformer oils. The method is based in the PCBs liquid-liquid extraction from oil transformer using n-hexane as solvent and the later determination of PCBs for gas chromatographic with flame ionization detector. Aroclor 1254 was used as secondary standard. To evaluate the linearity of the system and the method seven dissolutions between 10 and 1000 mu g/mL of concentration were prepared. The resulting calibration curve presents a lineal behavior in the studied interval of concentration with a correlation coefficient R-2 of 0.9992. The method shows a good reproducibility in the injection with a variation coefficient smaller that 5%, good exactitude and high recuperation percent. The detection limit was smaller than 20 mu g/mL. Finally, the method validated was used for the determination of PCBs concentration in oil samples from out of service transformers.
