Abstract
Inverse gas chromatography has been used to characterize changes of po re structure of active carbon preparations (commercial, ash-discharged and oxidized) polluted with tert-butylbenzene and regenerated by supe rcritical extraction with carbon dioxide. The slit-like model of micro pores has been applied for description of pore structure. Ash-discharg ed sample has proved to be the most difficult to regenerate by this me thod.
