Abstract

The effects of physico-chemical properties of soils on PCBs analysis in Korea was studied Three kinds of extraction solvents(toluene, acetone:hexane, dichloromethane) was selected to apply three different soils. The silicagel, florisil and alumina column cleanup also performed to compare the elution patterns, and three different methods (EPA, Japan, Proposed method in this study) of 62 PCBs also compared the individual peaks recoveries. The solvent average recovery was surveyed the order of toluene, acetone:hexane, dichloromethane as 77.94%, 58.59%, 54.20% for soil A, 53.65%, 80.32%, 68.27% for soil B and 44.52%, 60.35%, 56.36% for soil C, respectively. The average recovery was depended on the soil characters. The highest recoveries of each soil were obtained the toluene for soil A, acetone:hexane for soil B and C. However, the coplanar PCBs was obtained the highest recovery with dichloromethane. Thus, to select the solvent for the analysis of PCBs in solid, the selected compounds have to consider to get good result. The silicagel, florisil, alumina I and alumina II column cleanup process were surveyed the range of 38.73%~98.26%, and the higher chlorinated compounds was obtained the lower recovery compared to the low chlorinated compounds, generally. This results are also consistent with the coplanar PCBs isomers. The compared results of three different countries were obtained the 37.15% for USA, 45.92% for Japan and 44.46% for proposed method in this study.

본 이화학적 특성이 다른 토양 중 PCBs 분석에 대해 연구하기 위해, 세 종류의 우리나라 토양을 선정하여 용매별 (톨루엔, 아세톤:헥산, 디클로로메탄) 추출효율을 조사하였다. 또한, 실리카겔, 플로리실 및 알루미나 정제 컬럼을 이용한 용출패턴 특성을 조사하였으며, 현재 이용되고 있는 미국, 일본 및 우리나라 PCBs 시험방법을 우리나라 토양에 적용하여 분석결과를 비교하였다. 토양 중 62종의 PCBs 용매별 추출효율은, 톨루엔의 경우 토양 A, 토양 B 및 토양 C에 대하여 평균회수율은 각각 77.94%, 53.65% 및 44.52%로 나타났다. 아세톤:헥산 (1:1)의 경우에는 토양에 따라 각각 58.59%, 80.32% 및 60.35%로 나타났으며, 디클로로메탄의 경우에는 각각 54.20%, 68.27% 및 56.36%로 나타났다. PCBs 분석을 위한 정제컬럼별 용출효율은, 실리카겔의 경우 1Cl에서 10Cl의 평균회수율이 89.67% (1Cl)~44.85% (8Cl)로 나타났으며, 플로리실의 경우 1Cl에서 10Cl의 평균 회수율은 67.00% (8Cl)~98.26% (10Cl)로 나타났다. 또한, 알루미나의 경우 알루미나 I은 1Cl에서 10Cl의 평균 회수율은 63.01% (9Cl)~88.17% (1Cl)로 나타났으며, 알루미나 II는 1Cl에서 10Cl의 평균 회수율은 61.40% (7Cl)~80.78% (1Cl)로 나타났다. 미국, 일본 및 본 연구의 시험방법을 비교한 결과, 토양 A에 대한 62종의 PCBs의 평균회수율은 각각 37.15%, 45.92% 및 44.46%로 나타났으나, 시험방법에 따라 개별 피이크의 회수율은 비교적 큰 차이를 보이고 있다.
