Electrolysis with flowing solution

Abstract

A new type of electrolytic cell with a flowing solution is described. The working electrode is composed of a piece of 80-mesh platinum grid rolled together to form a plug. The electrolysed solution flows under gravitational force through the pores of the electrode. The reduction of K3Fe(CN)6 and of O2, and the oxidation of 9,10-diphenylanthracene, have been employed to test the operation of the cell. The limiting currents of the reduction and of the oxidation are practically linear with respect to the flow velocity. Several possible applications of the cell are listed.
