Abstract

The cyclic-magnetammetry (CM) to analyze electrochemical reactions in a magnetic field has been newly proposed; a periodically changing magnetic field is applied to a magnetohydrodynamic electrode (MHDE) in a vessel filled with an electrolyte solution. During the electrolysis under potentiostatic condition, current response is measured against magnetic flux density. Using the locus of the current against the magnetic flux density (the cyclic magnetammogram), we can examine the special magnetic field effects on the reaction and diffusion processes excluding the usual MHD effect. Experiments were carried out for redox reactions between ferricyanide and ferrocyanide, and copper reduction in sulfuric acid. It turned out that, in the former redox reaction, the locus converged to a straight line as expected. However, in the copper reduction, obvious hysteresis effect on magnetic field and periodic current response were observed.
