Abstract

Abstract: The CO2 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 plot provided information on the pore size distribution(PSD) of
a sample, which may be used to monitor the effect of activation conditions in activation
processes.

Key words: pore size distribution, activated carbon, CO2 adsorption, activation
