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.
