Aplicações eletroanalíticas com eletrodos de prata confeccionados a partir de CDs graváveis

Abstract: . Prof. Lineu Prestes, 748, 05508-900 São Paulo -SP Recebido em 13/12/02; aceito em 29/4/03 ELECTROANALYTICAL APPLICATIONS OF SILVER ELECTRODES BUILT FROM RECORDABLE CDs. This paper presents a new way for the construction of silver electrodes utilizing recordable CDs. The new electrodes were explored for the quantification of chloride (by potentiometry/FIA), cyanide (by amperometry/FIA) and for lead analysis (by square wave voltammetry). For the flowing measurements, a digital multimeter, connected to a microc… Show more

“…Once removed the exposed Au layer can be then used as the working electrode. Using a similar fabrication technique, Richter et al [26] in their pioneering work in 2003, showed a number of new applications that these CD electrodes could be employed for; including the quantification of chloride ions by potentiometry by flow injection analysis, cyanide by amperometry flow injection analysis and Pb by square wave stripping voltammetry.…”

“…Como consequência, têm mostrado alta versatilidade de aplicações, tanto na forma de eletrodo convencional, quanto na forma de eletrodo modificado. [21][22][23][24][25][26][27][28][29][30][31][32][33] Ademais, dependendo da aplicação, esses eletrodos podem ser empregados muitas vezes, barateando ainda mais o custo das determinações analíticas.…”

“…21,30,[35][36][37][38] CD-Rs possuem em sua constituição uma película metálica de ouro ou prata que, de forma adequada, são expostas e transformadas em eletrodos sólidos destes metais. A aplicação destes dispositivos já foi relatada em diversos trabalhos, tanto para a quantificação de traços de metais 35,36 como para a análise de fármacos.…”

“…This transduction can be carried out through a variety of physical and chemical principles, and in most cases, the resultant electrical quantity can be measured using a multimeter. Colorimetric (Acharya, Jayaraman, 1995;Richter, Rocha, Angnes, 2004;Rossi, He, Tubino, 2000;Wang, 2000), potentiometric (Barnard, 1968;Ooba, 1991;Richter, 2003;Sevilla, Alfonso, Andres, 1993;Vreman, 1994;Watanabe, 1997) and conductometric (Sevilla, Alfonso, Andres, 1993;Yue, Ngin, Hailin, 1996) systems based on a multimeter have been described in the literature.…”
