Abstract

Se proporciona un método para medir una concentración de especies electrolíticamente activas en una solución acuosa o no acuosa para el uso en la provisión de control de la concentración de la especie en una solución de origen de la misma basada en las mediciones. En el método, una muestra que contiene una especie electrolíticamente activa se adiciona en una celda de medición que tiene un electrodo de trabajo y un electrodo auxiliar, y una corriente constante se aplica a la celda de medición mientras que los electrodos de trabajo y auxiliares están en contacto con la muestra con el monitoreo de la diferencia de voltaje a través de los electrodos hasta que se detecta un cambio en la diferencia de voltaje. Una señal de retroalimentación se genera en base a un parámetro del cambio en la diferencia de voltaje que es directamente proporcional a la cantidad de la especie electrolíticamente activa en la muestra, que se puede utilizar para el control del proceso. También se describe un aparato.
