ABSTRACT
This chapter presents the fundamentals of various stripping procedures and discusses the instrumentation requirements, including the selection of the voltammetric analyzer, working electrode, cell, and other variables. Anodic stripping voltammetry involves the electrochemical oxidation of a preconcentrated analyte. Careful interpretation of the resulting current–potential peak shape on the voltammogram recorded during the stripping step allows one to obtain vital and desired analytical information. Cathodic stripping voltammetry is the “mirror image” of anodic stripping voltammetry. Adsorptive stripping voltammetry has extended the scope of stripping analysis toward numerous analytes. Many designs of electrochemical cells for stripping measurements have been reported in the literature or made available commercially. Chemically modified electrodes can add a new dimension to stripping analysis. In particular, the modification of electrode surfaces can provide alternative approaches for accumulation of surface-bound species, thus extending the scope of stripping measurements. The popularity of stripping analysis depends on the availability of suitable instrumentation.
