Surface Composition and Adsorption Properties of Activated Carbon Cloth

Surface properties of activated carbons have shown to play an important role in process. The presence of various functional groups (such as phenolic, carbonyl, ) on the carbon surface depends on the nature of its base component and the activation employed in the manufacturing process. aim of this work is to gain a better fundamental understanding of the nature of oxide sites present on activated carbon cloth surface (ACC), and their role in the process. BET surface areas of ACC were measured by means of benzene adsorption . The amount and the type of surface oxygen groups were determined by analysis and classical titration following Boehm’s method. Batch adsorption were used to evaluate equilibrium adsorption isotherms of phenol on ACC. was shown that both surface area and surface groups composition had impact on adsorption of ACC against phenol.
