WATER ADSORPTION ON ACTIVATED CARBONS: STUDY OF WATER ADSORPTION ON MICROPOROSITY AND MESOPOROSITY

摘要

The isotherm shape of water adsorption is influenced by the pore size distribution of the AC. On essentially microporous this are type V, while on AC with micro and mesoporosity the shape are a mixture of type Ⅲ and Ⅴ isotherms. This is related with the process of water adsorption. Thus, initially, water adsorbs preferentially on the micropores, while at higher P/Po this is realising on the mesoporosity.
