Abstract

The extraction methods of PBBs from environmental samples by soxhlet extraction for solid phase and liquid-liquid extraction for liquid phase were compared. After extraction, silicagel and florisil as column clean up methods were used for the comparison of cleanup efficiency with different solvent system. Also, the analytical instruments were used GC/MSD. The 22 kinds of PBBs standards were used to establish the analytical methods to perform the experiments of recoveries and detection limits in water and soil. The detection limits of PBBs represented 5~10 ng/L for water and 0.5~3.5 ng/g for soil samples, respectively. The recoveries of water samples represented 96~107% in n-hexane, dichloromethane and toluene for water, and 60~80% in combined solvent with n-hexane and acetone. The recoveries of soil sample were surveyed 67~97% in soxhlet extraction and 64~76% in ultrasonic extraction with selected solvents.

수질 및 토양 시료 중의 PBBs의 분석방법 확립을 위해 표준물질이 준비된 PBBs 22종을 대상으로 추출 및 정제 등의 전처리 회수율 및 검출한계를 환경시료로부터 얻었다. PBBs의 시료 추출법으로 액/액, 속실렛, 초음파 추출법을 적용하였고, 실리카겔, 플로리실 정제컬럼의 적용성 검토 후 GC/MS로 분석하였다. 수질 시료의 경우 검출한계는 브롬화된 정도에 따라 약간의 차이를 보였고 5~10 ng/L이었으며, n-hexane, dichloromethane 및 toluene 등의 단일 용매의 평균회수율은 96~107%, n-hexane:acetone (1:1) 및 (9:1)의 혼합용매의 평균 회수율은 60~80%로 나타났다. 또한, 토양 시료의 경우 검출한계는 0.5~3.5 ng/g이었으며, 선정 용매의 평균 회수율은 속실렛 추출이 67~97% 및 초음파 추출이 64~76%로 나타났다.
