Abstract
La presente invencion se refiere a procedimiento para la obtención de dicromatos alcalinos y ácido crómico mediante elactrólisis de soluciones de monocromatos y/o dicromatos de células electrolíticas, y cuyas cavidades anódicas y catódicas están separadas por medio de membranas intercambiadoras de cationes, el procedimiento está caracterizado porque se envía continuamente a la actividad catódica una solución que contiene cromato con un valor del pH de aproximadamente 3 a 10.
