Abstract
A novel application of adsorption isotherms has been developed to determine the position of the primary water-adsorbing centres within the porous structure of active carbons. Naphthalene was pre-adsorbed to partially fill the micropores. The number of primary adsorption centres was determined by application of the Langmuir and modified Dubinin–Serpinsky equations to water isotherm data measured on the pretreated carbons.
