Abstract

In this study, soxhlet extraction and dissolution-precipitation method are used for separating analyte from polymer materials. In soxhlet extraction efficiency test, it has been found that the DCM, Toluene, THF, and mixtures Acetone/Hexane (1:4, v/v) gave good extraction efficiency, while the use of the ethyl ether, acetone/ethyl ether (1:4, v/v), acetone/hexane (1:1, v/v), DCM/hexane (1:1, v/v) resulted in significantly lower values. In case of dissolution-precipitation method, there is no considerable difference with used different dissolving solvent. The elution amount of multi layer silica and Florisil column were determined with hexane 250 mL and 70 mL of hexane, respectively. Range of PBDE in real waste plastics was N.D.~1,028 ppm.

본 연구에서는 폴리머 재질로부터 시료를 분리하기 위하여 속실렛 추출방법과 용해-침전법이 적용되어졌다. 속실렛 추출의 경우 DCM, Toluene, THF, Acetone/Hexane (1:4, v/v)의 용매가 높은 효율을 나타내는 반면, ethyl ether, acetone/ethyl ether (1:4, v/v), acetone/hexane (1:1, v/v), DCM/hexane (1:1, v/v) 용매는 낮은 효율을 보였다. 용해-침전 방법의 경우 용해를 위해 사용된 용매에 따른 차이는 없었다. 다층실리카겔 컬럼과 플로리실 컬럼의 분획실험 결과 각각 hexane 250 mL와 70 mL로 최적 용래량이 결정되었다. 실제 폐 플라스틱 분석 결과 N.D.~1028 ppm인 것으로 조사되었다.
