Abstract:

The surface chemincal species of surface-modified activated carbons and ad sorption of 12-silicotungstic acid (SiW_(12)) on them were studied It was found that these carbons have different adsorption isotherms and adsorptive force. The carbonyl groups on the surface of activated carbon were favorable while carboxyl groups were unfavourable for the adsorption of SiW_(12).

Key words: Activated carbon, Adsorption, Heteropolyacids, Heterogenization
