The CO2 adsorption data may show more than one section in theDubinin-Radushkevich-Kaganer(DRK) plot ifsamples had been over-activated. Each section in the plot represents arange of pore size.The whole DRK plot provided information on the pore size distribution(PSD)of a sample, which may be used to monitor the effect of activationconditions in activation processes.
