Abstract:

In order to define the force of heteropoly acids on adsorbed activated carbon surface, IR spectra of 12-silicotungstic acid (SiW12) and 12-tungstophosphoric acid(PW12) adsorbed on activated carbon and in oxygen-containing orgainc compound solutions were studied. Based on the IR spectra and UV characteristics of the heteropoly acids in various chemical conditions, the chemical bonding between heteropoly acid and oxygen-containing groups on the surface of activated carbon was suggested.

Key words: Activated carbon, Heteropoly acid, Adsorption
