Abstract

EN UN PROCEDIMIENTO PARA MEDICION ELECTRICA DE CONCENTRACION DE ACIDOS SE COLOCA UN ELECTRODO DE MEDICION (11) COMPUESTO DE GRAFITO CRISTALINO PREDOMINANTEMENTE EN UN ACIDO (12) QUE MUESTRA ANIONES FORMADOS CON COMBINACIONES DE GRAFITO E INTERCALACIONES DE GRAFITO. EL ELECTRODO DE MEDICION (11) SE INTERCALA SEGUIDAMENTE MIENTRAS EN EL ELECTRODO DE MEDICION (11) EN POTENCIAL POSITIVO VARIABLE SE PRODUCE UNA CORRIENTE DE TAL MAGNITUD QUE LOS ANIONES DEL ACIDO (12) PUEDEN FORMAR CON EL GRAFITO COMBINACIONES DE INTERCALACIONES DE GRAFITO. LA CORRIENTE SE MANTIENE DURANTE EL TIEMPO HASTA QUE SE HAYAN FORMADO SUPERFICIALMENTE LAS COMBINACIONES D EINTERCALACIONES. SEGUIDAMENE SE MIDE EL POTENCIAL EN EL ELECTRODO DE MEDICION (11) Y SE UTILIZA COMO MEDIDA PARA LA CONCENTRACION DE ACIDOS. FINALMENTE SE VUELVE A DESINTERCALAR EL ELECTRODO DE MEDICION (11).
