✦ Synopsis


Linear sweep voltammograms for the dissolution of electrodcposited nickel indicate that a mixture of two nickel phases is usually deposited. These two phases have bezn identified as hydrogen-rich p-nickel and the solid solution a-nickel. The anodic charges obtained for each oF these have been used in the analysis OF the cathodif: transient. The partial transient for u-nickel appears to obey the laws for threedimensional growth and progressive nude&ion. In the partial transient for /?-nickel mass transfer of hydrogen ions becomes a rate-determining factor. The latter appears to be responsible for the maxima in the cathodic transients.
