【 摘 要 】

The aim of this work is to discuss some selectedapplications of square wave voltammetry published in the last five years. Theapplications focused here cover several electroanalytical fields such as: determinationof pesticides; molecules with biological activity; metals and other environmentalpollutants. Special attention is given to the work developed in the Grupo deMateriais Eletroquímicos e Métodos Eletroanalíticos – IQSC– USP concerning the utilization of square wave voltammetry, with differentkinds of electrodes, for the determination of pesticides in natural waters andactive principles in pharmaceutical formulations. The new methodology is simple,fast and sensitive when compared with the traditional ones such as chromatographyand spectrophotometry. The satisfactory results obtained provide alternativeprocedures for the quality control of drugs and the monitoring of pesticidesin natural environments.
