ELECTRICAL-CONDUCTION OF ELECTROLYTE-SOLUTIONS IN NONPOLAR LIQUIDS

Certain nonpolar liquids, when doped with specific salts, are able to produce sustained and reproducible ion injections from one of the elec trodes. Electronic transfer to the ionic pairs attached to the electro des and the subsequent extraction of the free ions by the Schottky eff ect are the mechanisms responsible for this injection. The electrical conduction of these liquids is studied, using a recently proposed elec tric-field dependent law for the injection of ions and Onsager theory for the dissociation of ionic pairs in the bulk. Recombination is allo wed between electrolytic ions and injected ions. The current-voltage c haracteristics predicted with this model have been presented in term o f dimensionless parameters, so that an easy comparison with experiment s can be done. Special attention has been paid to distinguish the cont ribution of the dissociation and the injection in the total current. T he electric field distortion and the charge density at the injector ha s also been determined.
