Abstract

RESUMEN Objetivo: En este trabajo se realiza, por primera vez, la evaluación teórica de la posibilidad de la detección electroanalítica de salvarsano, fármaco antisifilítico. El oxihidróxido de cobalto, en su compuesto con el colorante escuárico, se usa como modificador de electrodo. Metodología: Mediante el análisis de estabilidad, se ha confirmado su eficiencia en los procesos de detección de salvarsano. La linearidad de dependencia entre el parámetro electroquímico y la concentración del fármaco se obtiene y se mantiene fácilmente. Conclusión: Las inestabilidades oscilatoria y monotónica se realizan en el sistema, causadas por las influencias de las etapas electroquímicas a las capacitancias de la doble capa eléctrica (DCE). SUMMARY Aim: In this work, the theoretical evaluation of the electroanalytical detection of antisyphilitic drug salvarsan is given for the first time. Cobalt oxyhydroxide in a composite with the squaraine dye is used as electrode modifier. Methodology: By means of the stability analysis the efficiency of the salvarsan determination is confirmed. The linearity of the dependence between the electrochemical parameter and drug concentration is easily obtained and maintained. Conclusion: The oscillatory and monotonic instabilities are realized in this system, being caused by the electrochemical stages' influences to the double electric layer (DEL). RESUMO Objetivo: neste trabalho, a avaliação teórica da detecção eletroanalítica do antissifilítico salvarsan é feita pela primeira vez. O oxihidróxido de cobalto em um composto com o corante esquaraína é usado como modificador de eletrodo. Metodologia: por meio da análise de estabilidade é confirmada a eficiência da determinação de salvarsan. A linearidade da dependência entre o parâmetro eletroquímico e a concentração do fármaco é facilmente obtida e mantida. Conclusão: as instabilidades osci-latórias e monotônicas são percebidas neste sistema, sendo causadas pelas influências dos estágios eletroquímicos sobre a dupla camada elétrica (DEL).
