Adsorption from binary solutions of benzene and cyclohexane on cobalt-chalcogenide surfaces

Adsorption equilibrium for binary mixture of benzene and cyclohexane with cobalt chalcogenides has been studied at 30°C. Benzene is preferentially adsorbed on the cobalt oxide surface, whereas cyclohexane is preferentially adsorbed on the cobalt sulfide surface. The adsorption on the cobalt selenide...

Description
Summary:Adsorption equilibrium for binary mixture of benzene and cyclohexane with cobalt chalcogenides has been studied at 30°C. Benzene is preferentially adsorbed on the cobalt oxide surface, whereas cyclohexane is preferentially adsorbed on the cobalt sulfide surface. The adsorption on the cobalt selenide and cobalt telluride surfaces is negligible due to their low surface area. The adsorption equilibrium data for cobalt oxide and cobalt sulfide surfaces have been analysed on the basis of two different approaches, vis., the Schay and Nagy model and Everett's Perfect Solution model. Surface areas computed from the Schay and Nagy model shows good agreement with BET values.
