Abstract

La invención proporciona métodos y composiciones para la detección y la remoción de sulfato de un líquido. El método proporciona remoción mucho más rápida de sulfato que la técnica anterior y lo hace aun requiriendo el uso de mucho menos aluminio. El método involucra la adición secuencial al líquido de un agente de aluminio que genera pH de ácido a neutro, un agente de aluminio que genera pH alcalino, después que se ha agregado al líquido el agente de aluminio que genera pH de ácido a neutro, y un agente de calcio alcalino. La velocidad más eficiente posible puede obtenerse también al usar un fluoróforo para determinar con mayor precisión determinar la cantidad de sulfato en el líquido.
