Reference data for the adsorption of dichloromethane on carbon materials

The adsorption of dichloromethane at 298K on non-porous carbon blacks and m icroporous activated carbons, including Takeda molecular sieves and Maxsorb superactivated carbons, has been studied. The results suggest that the exa ct shape of the isotherm on non-porous carbons is sensitive to the degree o f uniformity of the surface and that it is therefore not possible to define a universal standard dichloromethane isotherm. On the other hand, it is po ssible to define reference data which can be used to analyse adsorption iso therms of dichloromethane determined on non-porous and microporous carbon m aterials by means of the alpha method. An indication of the range of applic ability and the likely precision obtained when using the data is given. (C) 2001 Elsevier Science Ltd. All rights reserved.
