Supporting Electrolytes for Voltammetric Study of Ion Transfer at Nitrobenzene/Water Interface

Abstract

The polarizable potential range was determined by cyclic voltammetry for the interface between an aqueous solution of lithium chloride or magnesium sulfate and a nitrobenzene solution of various electrolytes: tetrabutylammonium salts of tetraphenylborate, tetrakis(4-fluorophenyl)borate, tetrakis(4-chlorophenyl)borate, and tetrakis[3, 5- bis(trifluoromethyl)phenyl]borate, and tetrapentyl- and tetrahexylammonium salts of tetraphenylborate. The anodic and cathodic limits of polarizable potential range were discussed with reference to the standard ion-transfer potentials of the supporting-electrolyte ions.
