Abstract

La invención se refiere a un método para determinar la concentración libre de cloro en una primera solución líquida (11), que comprende las siguientes etapas: • una primera etapa (101) para introducir la primera solución líquida (11) en un analizador (12) que comprende una sonda redox (16), • una segunda etapa (102) para medir el pH de la primera solución líquida (11), • una tercera etapa (103) de adición de hidróxido de sodio hasta que se produzca una segunda solución líquida (15) con un pH superior a 12, preferentemente de 12,5 a 12,8), la tercera etapa (103) que se realiza preferentemente al mismo tiempo que la segunda etapa (102), • una cuarta etapa (104) para determinar un valor del potencial redox de la segunda solución líquida (15) por la sonda redox (16), • una quinta etapa (105) para determinar la concentración libre de cloro en la primera solución líquida (11) según el valor del potencial redox determinado. La invención también se refiere a un dispositivo para determinar la concentración libre de cloro de una primera solución líquida.
