Voltametria de onda quadrada. Segunda parte: aplicações

Abstract: 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 Materiais Eletroquími… Show more

“…8,[21][22][23] The response obtained by square-wave voltammetry is dependent on parameters such as frequency (f), pulse height (DE p ) and scan increment (DE s ), which have a combined influence on the peak current. Hence, they were analyzed in order to optimize the experimental set-up for sulfadiazine determination.…”

“…Em geral, as respostas obtidas com a utilização de técnicas eletroanalíticas sofrem uma menor influência de interferentes presentes nas amostras, comparando-se com técnicas cromatográficas, o que tem possibilitado o uso destas técnicas na análise de pesticidas [21][22][23][24][25][26] . Atualmente, a sensibilidade das técnicas eletroanalíticas é comparada à de qualquer técnica cromatográfica e espectroscópica.…”
