Magnetoelectrolysis of copper

The effect of a uniform static magnetic field on processes occurring at Cu/ acidified CuSO4 interfaces is examined by analysis of potentiodynamic polar ization curves. The mass transport controlled deposition current is increas ed by as much as a factor of 2 in a 0.6 T field, independent of field direc tion and electrode orientation. The extent of current enhancement is greate st at low pH (<1), where it is associated with diffusional rather than migr ational transport of the copper ions. (C) 1998 American Institute of Physic s.
