15 cc/g or more, a weight average particle size of less than 140 microns, and a differential characteristic curve of pore volume versus adsorption potential
by the GAED or equivalent method having a peak value at less than 5 cal/cc.
i] adsorption potential of all ionic species, F Faraday constant, [Mathematical Expression Omitted] molar fraction of the ionic species in the shear plane, [e.
the adsorption potential for all ionic species [[Phi].
According to Lyklema, adsorption potentials and pK values are correlated by (17):
Adsorption potentials calculated by the Jacobasch model are in a good agreement with the results obtained by spectroscopically determined adsorption isotherms.
