Changes in the Surface Chemistry and Adsorptive Properties of Active Carbon Previously Oxidised and Heat-Treated at Various Temperatures. II. Electrochemical Investigations of Surface Chemistry
Thermal treatment of oxidised active carbon under vacuum conditions led to changes in the chemical nature of its surface, e.g. a stepwise decrease in the total oxygen content and an increase in the pH of the carbon slurry. Annealing reduced the number of surface oxygen-containing groups and increase...
