Abstract

La presente invención, se refiere a un procedimiento para la obtención de un electrodo de carbono proveniente de desechos de pilas ácidas con altísima actividad electrocatalítica y que puede usarse como cátodo o ánodo para diversas aplicaciones como en electroquímica, galvanoplastia, refinación electrolítica, etc. Una de sus aplicaciones más interesantes es en el campo de los electrodos sensores. El proceso comprende las etapas de: a) extracción del carbono de la pila y luego sacar su recubrimiento; b) hervir en agua destilada entre 5 y 30 minutos; c) lavar el electrodo con detergente preferentemente neutro; d) lijar y lavar con agua hirviendo y luego con detergente hasta no obtener residuo; e) sonicar entre 5 a 30 minutos en agua destilada; f) someter el electrodo a lavado con éter de petróleo u otro solvente altamente apolar; g) sonicar y lavar con solventes orgánicos de menor a mayor polaridad, cambiando el agua, hasta llegar a agua limpia; h) hervir el electrodo en una solución que contenga un oxidante fuerte y pH ácido durante 5 minutos a una hora; i) repetir el procedimiento de lavado y sonicado si es necesario; j) pulir de manera convencional para su uso; y k) si se desea se puede insertar en teflón o PVC para aislar parte de la superficie. La unión eléctrica se puede realizar haciendo un hilo interno al carbón.
