Descargas
La posibilidad de usar el oxihidróxido del cobalto en la detección electroquímica de la gabapentina ha sido evaluada, y se sugirió un mecanismo del desempeño del analito y del modificador. Este fue desarrollado y analizado (mediante la teoría de estabilidad lineal y análisis de bifurcaciones) un modelo matemático basado en este mecanismo. La evaluación teórica confirma que el oxihidróxido de cobalto puede ser un modificador eficiente para la detección de la gabapentina, a pesar de la hibridez de su mecanismo de oxidación. La posibilidad y las causas de los comportamientos oscilatorio y monotónico también han sido investigadas.
The possibility for the use of cobalt (III) oxyhydroxide in gabapentine electrochemical determination has been evaluated. A mechanism for analyte and modifier function has been suggested. A mathematical model based in this mechanism has been developed and analyzed (by means of linear stability theory and bifurcation analysis). The theoretical evaluation confirms that the cobalt (III) oxyhydroxide may be an efficient modifier for gabapentine electrochemical determination, despite of the hybridity of its oxidation mechanism. The possibility and the causes for oscillatory and monotonic instabilities have also been investigated.
