Electrolytic Chromatography and Coulopotentiography – A Rapid Electrolysis at the Column Electrode used for the Preparation, Separation, Concentration, and Estimation of Trace and/or Unstable Substances

I. INTRODUCTION

This article deals with a new analytical methodology based on rapid electrolysis on one hand and liquid phase chromatography on the other. From the standpoint of rapid electrolysis, many attempts in the instrumentation have been made. Eckfeldt¹ used a small cell (1.5 ml) with a working electrode of relatively large surface area to achieve a rapid electrolysis and determined iodide and dissolved oxygen in a flowing sample. In 1963, Fujinaga with other collaborators² investigated a rapid electrolysis at a series of column electrodes with silver grain as the electrode material. The electrode potentials of column electrodes were kept at different potentials. They termed the procedure "electrolytic chromatography" and quantitatively separated copper, lead, and cadmium by the method.
