Abstract

An active, commercial-grade carbon, washed with boiling 1 M HCl, to eliminate ash from its surface, was thermally treated in the presence of oxygen at temperatures between 400 and 750 °C, to produce carbon samples whose capacity to adsorb SO2 was investigated. The amount of SO2 adsorbed appears to be closely connected to the basic surface properties of the carbons, measured in terms of benzoic acid adsorption.
