Catalytic systems in adsorptive stripping voltammetry

Catalytic adsorptive stripping voltammetry (CAdSV) combining adsorptive pre concentration of the electroactive species with the catalytic reaction prov ides a significant enhancement of the voltammetric response, and consequent ly a considerable decrease of the detection limit, as well as the improveme nt of the selectivity of the determination. This article presents principle s, potentialities and limitation of the CAdSV method. Depending on the mech anism and nature of the catalytic reaction applied in CAdSV the authors dis tinguish six basic types of the catalytic systems. The features and advanta ges of the above kinds of the catalytic systems are discussed. Basing on th e authors' investigations and the literature review, numerous examples of t he CAdSV systems, which have found wide application in ultratraces analysis , are presented. The future trends and development of the method are evalua ted.
