The CO_2 adsorption data may show more than one section in the Dubinin-Radushkevich-Kaganer(DRK)plot if samples had been over-activated.Each section in the plot represents a range of pore size.The whole DRKplot provided information on the pore size distribution(PSD)of a sample,which may be used to monitor the effectof activation conditions in activation processes.

The CO 2 adsorption data may show more than one section in the Dubinin-Radushkevich-Kaganer (DRK) plot if samples had been over-activated. Each section in the plot represents a range of pore size. The whole DRK map provides information on the pore size distribution (PSD) of a sample, which may be used to monitor the effect of activation conditions in activation processes.
