Ns. Polyakov et al., THE INFLUENCE OF LOW-TEMPERATURE OXIDATION OF ACTIVE CARBONS BY NITRIC-ACID ON THEIR PHYSICOCHEMICAL PROPERTIES, Russian chemical bulletin, 45(5), 1996, pp. 1071-1077
The influence of oxidation by nitric acid on the character of oxygen-c
ontaining functional surface groups and porous structure of active car
bons is considered. Adsorption properties of the initial and oxidized
carbons are studied using adsorption isotherms of vapor of n-hexane an
d polar substances (water and methanol).
