Abstract

Gas chromatograph equipped with ECD (Electron Ionization Detector) was used to investigate the adsorption characteristics of 1,2-dichlorobenzene, which has a similar structure with dioxin, on graphite. Equilibrium adsorption constants of 1,2-dichlorobenzene on graphite were measured as 10.333, 6.167 and $4.270m^3/kg$ at 220, 240, $260^{\circ}C$, respectively. The isosteric heat of adsorption of 1,2-dichlorobenzene on graphite was 11.554 kcal/mol. This was because specific surface area was low and the amount of surface functional groups was small.

ECD가 장착된 기체크로마토그래프를 이용하여 다이옥신과 구조적으로 유사한 1,2-디클로로벤젠의 그래파이트 흡착특성을 고찰하였다. 그래파이트에서 1,2-디클로로벤젠의 평형흡착상수는 흡착온도 220, 240, $260^{\circ}C$에서 각각 10.333, 6.167, $4.270m^3/kg$ 값을 나타내었다. 표면 흡착열은 11.554 kcal/mol로 나타났으며 이는 그래파이트의 비표면적이 작고 표면기능기의 양이 적었기 때문이다.
