## Abstract The influence of thermal and chemical treatments (tetrahydrofuran and dioxane) on the adsorption properties of polyvinylchloride is investigated by gas chromatographic methods. It is shown, that heating to the glassβtransition temperature has an erasing effect. Methanol was used as the
The surface chemistry and the porous texture of activated carbons prepared from a charred product (C,,,-600), which was obtained from rockrose (Cistus ladaniferus, L.) extracted previously into petroleum ether, were studied. Activated carbons were prepared by heating C,,,-600 between 350 and 850Β°C i
