Abstract
본 연구에서는 PCBs 함유 폐기물의 분해 전후의 처리효율을 검토하고 반응 부산물을 확인하고 자 물리화학적 처리기술을 적용한 전자빔과 탈염소화 처리 전후의 시료를 분석하였다. 전자빔으로 물리 적 처리를 한 시료는 절연유 중의 PCBs 피크패턴을 유지하고 있지 않아 폐기물공정시험방법으로 정량 하기 어려워 HRGC/HRMS을 이용하여 정량한 결과, PCBs의 제품이 가지고 있는 피크패턴이 분해되어 저염화물인 3-chlorobiphenyls이 생성되는 것으로 확인 되었다. 또한, 탈염소화 분해로 화학적 처리한 경 우에도 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.
