The reversible reduction of Cd(II) in 1 M NaCl has been considered using theory based on digital simulation. Differential pulse peak currents and positions are influenced by amalgam formation coupled with spherical diffusion, and this is considered in relation to the results of previous investigations. Spherical diffusion is not experimentally significant except at short drop times where distortion arising from dc terms are present. For quasi-reversible electrode processes the influence of spherical diffusion and amalgam formation is demonstrated to be considerably more important than for the reversible case.
