Abstract

PROCESO Y DISPOSITIVO DE MEDIDA DE LA CONCENTRACION DE CO2 DISUELTO EN AGUA DE MAR, EN EL CUAL SE REALIZA UNA MEDIDA DEL PH POR COLORIMETRIA SOBRE UNA SOLUCION CUYA CONCENTRACION DE CO2 SE EQUILIBRA CON LA DEL AGUA DE MAR. SE HACE UNA MEDIDA DE LA ABSORBENCIA OPTICA DE LA SOLUCION CON UNA LONGITUD DE ONDA ( M) CARACTERISTICA DE UN MAXIMO DE ABSORCION DE ONDA ( B) EN LA CUAL EL COLORANTE NO ABSORBE; UNA MEDIDA DE ABSORBENCIA COMPLEMENTARIA CON UNA LONGITUD DE ONDA ( I) HACIA EL PUNTO ISOBESTICO DEL COLORANTE. EL DISPOSITIVO COMPRENDE UNA CELULA DE MEDIDA (3) QUE INCLUYE LA SOLUCION CON INDICADOR COLOREADO Y UNOS MEDIOS (26, 27A, 27B, 27C) PARA FILTRAR SUCESIVAMENTE EL HAZ OPTICO DE SALIDA DE LA CELULA (3) EN LAS DIFERENTES LONGITUDES DE ONDA NECESARIAS PARA REALIZAR LAS MEDIDAS SEGUN EL PROCESO.
