A modified I-method known as t/J method, capable of finding mesopore surface area in absence or oresence of micropores in which adsorption may be oressure dependent or pressure independent is described by the application of John's adsorption isotherm equaiion.
Three different types of carbon precursor-mesophase microbeads, preoxidized polyacrylonitrile (PAN) fibres, and phenolic fibres-have been carbonized in argon at 900Β°C and thereafter activated with carbon dioxide at the same temperature.
