Abstract

LA PRESENTE INVENCION PROPORCIONA UN SENSOR, PREFERIBLEMENTE UN SENSOR ELECTROQUIMICO, PARA DETECTAR GASES ACIDOS, POR EJEMPLO DIOXIDO DE CARBONO. EL SENSOR ELECTROQUIMICO TIENE UN ELECTRODO SENSIBLE (20, 22), UN ELECTRODO CONTADOR (37) Y UN ELECTROLITO QUE CONTIENE UN COMPLEJO, POR EJEMPLO, BIS(PROPANODIAMINA) DE COBRE(II), QUE TIENE UNO O MAS LIGANDOS DESPLAZABLES POR LA PRESENCIA DEL GAS ACIDO EN EL ELECTROLITO PARA FORMAR UN COMPLEJO MODIFICADO QUE PUEDE SER ELECTROQUIMICAMENTE REACTIVO EN EL ELCETRODO SENSOR A UN POTENCIAL AL QUE EL COMPLEJO NO MODIFICADO NO ES REACTIVO. EL GAS ACIDO DIFUNDE EN EL ELECTROLITO A TRAVES DE UNA MEMBRANA PORORSA. EL COMPLEJO MODIFICADO TAMBIEN SE PUEDE DETECTAR COLORIMETRICAMENTE DEBIDO A QUE ABSORBE LUZ A UNA LONGITUD DE ONDA DIFERENTE QUE EL COMPLEJO NO MODIFICADO.
