The textural structure and the surface property of activated carbon were selectively modified by KMnO 4 oxidation. The activated carbon treated by KMnO 4 oxidation in an acidic solution showed greatly enhanced H 2 O 2 production by hydroxylamine oxidation due to the creation of more surface quinoid
The process of adsorptive-catalytic cleaning of gas from sulfur dioxide using active carbon, treated by concentrated nitric acid, was studied. After oxidative treatment the acidity of the carbon increases and the basicity decreases. This results in an increase of the SO, adsorption and its oxidation
