Abstract

SE DESCRIBE UN METODO Y DISPOSITIVO PARA MEDICIONES ELECTROQUIMICAS CUANTITATIVAS IN SITU EN AGUA A ALTAS TEMPERATURAS. AL MENOS DOS PARES DE ELECTRODOS SE DISPONEN PARA DETERMINAR SIMULTANEAMENTE LOS CONTENIDOS DE DOS MOLECULAS O IONES, DISUELTOS EN EL AGUA, POR MEDIO DE UN METODO DE MEDICION ELECTROMECANICA EMPEZANDO POR LAS MEDICIONES DEL COMPORTAMIENTO CINETICO, ADSORCION O DIFUSION DE LAS MOLECULAS/IONES EN CONEXION CON LAS REACCIONES ELECTROQUIMICAS SOBRE O ADYACENTES A LOS ELECTRODOS METALICOS. SEGUN ESTA INVENCION, LAS REACCIONES ELECTROQUIMICAS PARA LAS MOLECULAS/IONES SON DETERMINADAS POR UN PRIMER PAR DE ELECTRODOS (21) QUE CONSTAN DE ELECTRODOS METALICOS DE UN METAL INERTE (211, 212), PREFERENTEMENTE METAL ORO O PLATINO Y UN SEGUNDO PAR DE ELECTRODOS (22) COMPRENDIENDO UN ELECTRODO DE UN METAL INERTE (212) Y UN ELECTRODO METALICO (222) QUE ESTA DOTADO CON UNA CAPA SUPERFICIAL (225). ESTA SUPERFICIE ESTA ADAPTADA PARA INFLUENCIAR LA CONDUCTA CINETICA, ADSORCION, Y DIFUSION EN RELACION CON UNA REACCION ELECTROQUIMICA DE LA SEGUNDA MOLECULA/ION DE TAL MANERA QUE LA SENSIBILIDAD DE LAS REACCIONES DE LA PRIMER MOLECULA/ION ES ESENCIALMENTE LA MISMA PARA AMBOS PARES DE ELECTRODOS, MIENTRAS QUE LA SENSIBILIDAD DE LAS REACCIONES DE LA SEGUNDA MOLECULA/ION DIFIERE CONSIDERABLEMENTE DEL PAR DE ELECTRODOS, PERMITIENDO, DE ESTA MANERA, DISTINGUIR LAS DOS MOLECULAS/IONES.
