dc.description.abstract | Coulometry is one of the analytical techniques used by the National Metrology Institutes as a pure substance analysis tool, and they are being accepted and implemented in chemical analysis laboratories. This document presents a review of the coulometric titration method with emphasis on constant current coulometry, as a technique of special interest for the determination of the amount of substance, recognized by the Consultative Committee for Amount of Substance: Metrology in Chemistry (CCQM) as a potential technique to be considered primary method of measurement. The document is organized in four chapters: in chapter one a description is made of the analytical methods, especially electrochemicals and their usefulness in the metrological area. A comparison is made between chemical and physical measurements and a description of the measurement methods and the importance of the primary measurement methods for the determination of the amount of substance. In chapter two, coulometry is presented as an analytical technique, types of coulometry, characteristics and variants of each. Chapter three documents the constant current coulometry, showing the different instruments used to perform the measurement, such as electronic equipment, indicator electrodes and the titration cell where the electrochemical reaction is carried out. Finally, chapter four is presented, dedicated to the evaluation of the possible sources that can contribute to the estimation of uncertainty in measurement in a coulometric titration at constant current, which can be taken into account in a future implementation of the method of coulometric measurement |

En el presente documento se presenta una revisión del método de titulación coulométrico haciendo énfasis en coulometría a corriente constante, como técnica de especial interés para la determinación de la cantidad de sustancia, reconocida por el Comité Consultivo para la Cantidad de Sustancia: metrología en química (CCQM por sus siglas en inglés) como técnica potencial para ser considera método primario de medición. El documento está organizado en cuatro capítulos: en el capítulo uno se realiza una descripción de los métodos analíticos, especialmente los electroquímicos y su utilidad en el área metrológica. Se hace una comparación entre las mediciones químicas y físicas y se presenta una descripción de los métodos de medición y la importancia de los métodos primarios de medición para la determinación de la cantidad de sustancia. En el capítulo dos, se presenta la coulometría como técnica analítica, tipos de coulometría, características y variantes de cada una. El capítulo tres documenta la coulometría a corriente constante, mostrando los diferentes instrumentos utilizados para realizar la medición, tales como equipos electrónicos, electrodos indicadores y la celda de valoración donde se lleva a cabo la reacción electroquímica. Por último, se presenta el capítulo cuatro, dedicado a evaluación de las posibles fuentes que puedan aportar a la estimación de la incertidumbre en la medición en una titulación coulométrica a corriente constante, las cuales pueden ser tenidas en cuenta en una futura implementación del método de medición coulométrico. |
