Abstract
SE DESCRIBE UN METODO PARA DETERMINAR LA PRESENCIA DE ION FERROSO EN EL AGUA DE LAS CALDERAS. EL METODO PUEDE UTILIZARSE PARA MEDIR DIRECTAMENTE EL GRADO DE CORROSION QUE OCURRE EN EL AGUA DE LAS CALDERAS, Y PUEDE MEDIR LOS NIVELES DE CORROSION EN LA PRESENCIA DE QUIMICOS DE TRATAMIENTO DE AGUA DE CALDERAS. EL METODO UTILIZA UN COMPLEJO FORMADO ENTRE SOLAMENTE ION FERROSO Y UN REACTIVO MONOHIDRATO DE ACIDO 3-(2-PIRIDILO)-5,6 -DIFENILO-1,2,4-TRIACINO-P,P''-DISULFONICO.
