摘要：
The electrolyte in the micropores of activated carbon, in contact with aqueous 0.3 M potassium fluoride solution and at zero charge potential, consists essentially of ion pairs along with merely 0.06 M free ions. The mobilities are 5 and 1.4 S cm(2) mol(-1) for K+ and F-, respectively. Exchange of ions with the external electrolyte, upon stepwise change of the electrode potential, was assisted by macropores.
