A typical activated carbon, derived from olive stones, has been oxidized to different degrees with (NH4)2S2O8 and analysed by water vapour adsorption, immersion calorimetry, acid–base titration and temperature-programmed desorption of CO2 and CO monitored by mass spectrometry. These techniques led to a coherent description of the surfaces...
