Abstract

METODO DE DETERMINACION DEL RENDIMIENTO DE UN AGENTE DE TRATAMIENTO (CA) AÑADIDO A UN CUERPO DE LIQUIDOS DEL SISTEMA A FIN DE MEJORAR EL RENDIMIENTO DEL CUERPO LIQUIDO. DICHO METODO SE DETERMINA MEDIANTE EL EMPLEO DE UN TRAZADOR FLUORESCENTE INERTE (T) DE UNA PROPORCION CONOCIDA DE DOSIFICACION T:CA, PREPARADA SEGUN UNA CONCENTRACION DE CA (POR EJEMPLO, PPM) PENSADA PARA UN RENDIMIENTO OPTIMO CON EL CUERPO LIQUIDO. SE TOMA UNA MUESTRA DEL LIQUIDO DEL SISTEMA Y, SEGUN LA EMISION FLUORESCENTE, EL INDICADOR DE LA MUESTRA SE COMPARA CON UNA CONCENTRACION PPM ESTANDAR DE T A FIN DE DETERMINAR LA CONCENTRACION Y EFICACIA DEL CA, ASI COMO LAS CARACTERISTICAS FISICAS Y PARAMETROS OPERATIVOS DEL CUERPO LIQUIDO.
