Abstract

SE DESCUBRE UN METODO Y APARATO PARA LA DETERMINACION ELECTROQUIMICAMENTE DE COMPONENTES ACTIVOS EN UN PROCESO EN CADENA. EL METODO COMPRENDE LOS PASOS PARA PROPORCIONAR UNA MUESTRA EN LA CUAL ESTEN CONTENIDOS LOS COMPONENTES, Y DEPOSITANDO LOS COMPONENTES DENTRO DE UN ELECTRODO DE TRABAJO ALTERANDO EL AMBIENTE DEL ELECTRODO DE TRABAJO A FIN DE QUE ESTE INMERSO EN UN SOPORTE ELECTROLITICO PARA EFECTUAR UN CAMBIO DE MATRIZ Y VACIAR EL DEPOSITO DE COMPONENTES ELECTROQUIMICAMENTE ACTIVOS DESDE EL ELECTRODO AL SOPORTE DEL MISMO. UN METODO Y APARATO QUE UTILIZA UNA CAVIDAD DE MEDIDA LA CUAL COMPRENDE UN RECIPIENTE (10) PARA CONTENER EL SOPORTE ELECTROLITICO Y UN ELECTRODO DE MERCURIO (150). UN INYECTOR DE FLUIDO (16) ES USADO PARA INYECTAR UN FLUIDO CON LA PRUEBA ELECTROLITICA DENTRO DEL RECIPIENTE PARA QUE LA PRUEBA ELECTROLITICA RODEE EL MERCURIO QUE REBOSE DEL ELECTRODO Y ENTONCES VIERTA EL MERCURIO SOBRANTE DEL ELECTRODO (150) A LA BASE DEL RECIPIENTE DONDE SERA TRASLADADO POR VIA DE UN DESAGUE (20) PARA, DE ESE MODO, PERMITIR AL ELECTRODO DE MERCURIO SUMERGIRSE EN EL SOPORTE ELECTROLITICO. LAS IMPUREZAS DEPOSITADAS SON DESECHADAS DEL SOPORTE ELECTROLITICO EMPLEANDO VACIADO VOLTAMETRICO DE TRANSITO ELECTROQUIMICO EN TIEMPO VARIABLE. LA SECUENCIA DE LOS PASOS INCLUIDOS EN LA ELIMINACION DE LAS IMPUREZAS DESDE EL INYECTOR DE FLUIDO DEL ELECTROLITO SON REPETIDAS BAJO CONTROL DE MICROPROCESADOR (50).FIG 2.
