摘要：

An equation for stripping polarographyis derived,relating the half-wave potential (E* 1 2), ligand concentration, and dissociation constant of a complexed metal ion. This equation is similar to that for classical polarography, but contains an additional term which makes (E* 1 2) a linear function of the logarithm of the time. A computer-assisted system for generating stripping polarographic curves is also described. This system is used to characterize 10-8 M cadmium in a potassium nitrate solution and in sea water. © 1979.
