Recebido em 3/10/03; aceito em 14/1/04; publicado na web em 17/6/04 SQUARE WAVE VOLTAMMETRY. SECOND PART: APPLICATIONS. The aim of this work is to discuss some selected applications of square wave voltammetry published in the last five years. The applications focused here cover several electroanalytical fields such as: determination of pesticides; molecules with biological activity; metals and other environmental pollutants. Special attention is given to the work developed in the Grupo de
more » ... the Grupo de Materiais Eletroquímicos e Métodos Eletroanalíticos -IQSC -USP concerning the utilization of square wave voltammetry, with different kinds of electrodes, for the determination of pesticides in natural waters and active principles in pharmaceutical formulations. The new methodology is simple, fast and sensitive when compared with the traditional ones such as chromatography and spectrophotometry. The satisfactory results obtained provide alternative procedures for the quality control of drugs and the monitoring of pesticides in natural environments.
