Abstract

SE AÑADE UN COLORANTE SOLUBLE EN AGUA, INERTE, A UNA COMPOSICION PARA TRATAMIENTO DE AGUA CONCENTRADA. ESTA MEZCLA SE AÑADE AL AGUA EN UN SISTEMA DE AGUA CIRCULANTE, TAL COMO UNA TORRE DE REFRIGERACION. LA CONCENTRACION DEL COLORANTE Y LA CONCENTRACION DE LAS SUSTANCIAS ACTIVAS EN LA COMPOSICION DE TRATAMIENTO SON PROPORCIONALES. LA CONCENTRACION DE LA COMPOSICION DE TRATAMIENTO EN EL SISTEMA ACUOSO SE PUEDE DETERMINAR MIDIENDO EL PORCENTAJE DE LUZ ABSORBIDA POR EL COLORANTE EN EL AGUA. ESTE SE PUEDE DETERMINAR MEDIANTE UN COLORIMETRO. LA FLUORESCEINA ES EL COLORANTE PREFERIDO.
