Adsorption of Water Vapor on a Graphitized Carbon Black.
Absorption isotherms for water vapor on a highly graphitized carbon black, Sterling FT-G (2700), have been determined at 280.15 and 295.15 K. Interparticle capillary condensation with extensive hysteresis is observed but capillary condensation (adsorption) occurs under metastable, supersaturation conditions. Contact angles for water adsorbed on this carbon black are calculated and two models for capillary condensation are discussed. Copyright 2000 Academic Press.
