The sorption of SO2 on the peat from different depths.

The determination of the sorption properties of peat from different depths was done. The research was carried out on the intermediate littoral peats near the Baltic Sea from the layers situated at every 0.5 m at depths up to 3 m . The effectiveness of peat sorbents has been detd. based on the isotherms of SO2, benzene, and CO2 sorption. This was done using the gravimetric method. The interpretation of the benzene sorption isotherms was carried out on the basis of the theory of volumetric filling of pores. These results were compared with respectively investigations on samples of steam-activated carbons (based on hard coal and wood tar) and demineralized brown coal.
