摘要
The adsorption and the desorption of SO2 on active carbons is studied in relation to the surface characteristics of the carbons. Surface basic groups (with pyronic or pyronic-like structure) greatly increase the adsorption of SO2, that can be divided into two forms, one weakly and the other strongly bonded to the carbon, referred to in this paper SO2 (a) and SO2 (b), respectively. The surface area of the carbon and the temperature of the process are the fundamental parameters of the desorption process of SO2. © 1990.
