Ohmic drop distortion of anodic stripping curves from a thin mercury-film electrode

Abstract

An exact treatment of the effect of uncompensated ohmic drop on anodic stripping curves from a plane, thin mercury-film electrode is given. The decrease in peak current caused by the ohmic drop can be 2.5–3 times larger than in the corresponding case of semi-infinite linear diffusion (“normal” linear-sweep voltammetry) Practical implications of the results, as well as the case of spherical micro-electrodes, are discussed briefly.
