Abstract
Summary A new device in hydrodynamic votammetry, termed a “wall jet electrode”, was presented, in which a jet of solution issued from a circular nozzle was allowed to impinge normally on a disk electrode. The construction and electrochemical properties of the wall jet electrode were described. A theoretical equation of the limiting diffusion current at the wall jet electrode was derived. The theoretical predictions for the dependence of the limiting diffusion current upon various experimental variables, i.e., the bulk concentration of depolarizer, the volume flow rate, the radius of the disk electrode, the diameter of the nozzle, etc., were verified experimentally.
