Zusammenfassung:The treatment efficiency of PCBs containing wastes has been investigated. The samples treated by electron beam and de-chlorination method were analyzed to verify the byproducts before treatment and after treatment. In the treated samples by electron beam irradiation, PCBs were not detected by comparing the peak matching using the Korean official waste test method. On the other hand, PCBs congeners were detected by analyzing individual isotope method using HRGC/HRMS. Most of PCB congeners in waste were decomposed to 3-chlorobiphenyls, lower chlorinated congener produced during the treatment of electron beam. In the chemical dechlorination treatment, it was found that the concentrations of PCBs in treated samples were lower than those of regulation criteria in Waste & POPs management law and the after treatment concentration were satisfied to the regulation criteria. Also, dioxins were not observed after the physio-chemical treatment processes of PCBs containing wastes. 본 연구에서는 PCBs 함유 폐기물의 분해 전후의 처리효율을 검토하고 반응 부산물을 확인하고자 물리화학적 처리기술을 적용한 전자빔과 탈염소화 처리 전후의 시료를 분석하였다. 전자빔으로 물리적 처리를 한 시료는 절연유 중의 PCBs 피크패턴을 유지하고 있지 않아 폐기물공정시험방법으로 정량하기 어려워 HRGC/HRMS을 이용하여 정량한 결과, PCBs의 제품이 가지고 있는 피크패턴이 분해되어 저염화물인 3-chlorobiphenyls이 생성되는 것으로 확인 되었다. 또한, 탈염소화 분해로 화학적 처리한 경우에도 PCBs 농도는 폐기물관리법 및 잔류성유기물질 관리법의 규제기준 이하로 POPs 관리법의 처리 종료 기준을 만족하는 것으로 나타났으며, PCBs 함유 폐기물을 물리화학적으로 처리하는 과정 중 분석 대상 모든 시료에서 다이옥신류가 불검출되어 다이옥신은 생성되지 않는 것으로 나타났다.
