Abstract
La presente invención se refiere a métodos y aparatos para la determinación de la relación de las formas oxidada y reducida de un par de redox en solución, cada método que comprende: (a) poner en contacto un primer electrodo activo estacionario y un primer contraelectrodo a la solución; (b) aplicar un primer potencial al primer electrodo activo y medir una primera corriente constante; (c) aplicar un segundo potencial en el primer electrodo activo y medir una segunda corriente constante; en donde el signo de las primera y segunda corrientes no es el mismo; y en donde la relación de los valores absolutos de las primera y segunda corrientes refleja la relación de las formas oxidada y reducida del par de redox en solución. Cuando se usa en el contexto de la supervisión/control de celdas electroquímicas, las modalidades adicionales incluyen las que comprenden además (d) oxidar o reducir la solución, con el fin de alterar el balance de las formas oxidada y reducida del par de redox en solución, en un grado que depende de la relación de los valores absolutos de las primera y segunda corrientes. Estas modalidades se pueden usar en el contexto de mantener una celda, pila, o sistema electroquímicos.
