what are differences between mechanism of heavy metal ions adsorption on activated carbon and mechanism of ion adsorption on volatege connected types of carbon electrodes?
Electrical field or functional group? Which factor really acts?
may a supercapacitor electrode without voltage absorbe ions?
Valence of ions are effective?
Raheleh Ebrahimi
Activated carbon adsorbs ions by the mechanism of ion - dipole intermolecular interaction. If a direct current is applied to it (placed in an electromagnetic field), then the ions begin to move towards this electrode. An redox reaction takes place. Thus, adsorption is a spontaneous process. The reaction takes place under the action of an electromagnetic field.
The voltage-free supercapacitor electrode can adsorb ions. The ion-dipole interaction of divalent ions is more efficient than that of monovalent ones.
