title: Determination of zinc in sea-water by anodic stripping voltammetry.
abstract: The horizontal distribution of zinc in surface waters from Guanabara Bay has been studied by use of optimized voltammetric techniques and ultraclean working procedures. The non-linearity observed between the peak current for zinc and the electrolysis time, as well as the appearance of a peak at -1.16 V, are discussed. The values found for total zinc in the samples range between 0.3 and 22 mug/l.
