Surface composition and adsorption properties of activated carbon cloth

Abstract

The aim of this work is to gain a better fundamental understanding of the nature Of Surface oxide sites present on activated carbon cloth (ACC) surface, and their role in the adsorption process. BET surface area of ACC was measured by means of benzene adsorption isotherms. The amount and the type of surface oxygen groups were determined by thermogravimetric analysis and titration following Boehm's method. Batch adsorption tests were conducted to evaluate equilibrium adsorption isotherms of phenol on ACC. It was shown that both surface area and surface groups composition had quite an impact on adsorption properties of ACC against phenol.
