| description |
El Glifosato es el herbicida más utilizado y comercializado a nivel mundial usado principalmente para el control de malezas. El uso excesivo y su impacto en el medio ambiente, ha promovido el análisis químico del Glifosato en el agua, el suelo y alimentos. Debido a la complejidad y características específicas de la molécula para ser analizada, es necesario implementar e introducir mejoras en las metodologías que permitan realizar procedimientos de detección a niveles de trazas. El Glifosato es un compuesto que no contiene una estructura química compleja, pero al tener cuatro grupos altamente polares, dificulta el análisis por métodos convencionales. Para la química, sigue siendo un desafío desarrollar técnicas que arrojen resultados confiables en tiempos cortos, teniendo en cuenta cada uno de los parámetros para que, en el momento de realizar la operación, el método elegido sea óptimo, confiable, eficaz y no se presenten errores en los procedimientos que pueden generar resultados incorrectos. Este trabajo se realiza a fin de recopilar las técnicas analíticas instrumentales usadas en la actualidad para la cuantificación y detección de Glifosato. Se describen los parámetros que deben ser relevantes para la determinación de Glifosato y su metabolito principal AMPA (ácido aminometilfosfónico) y procesos asociados a técnicas cromatográficas, que van desde rutas de degradación del contaminante, procedimientos de tratamiento de las muestras, reacciones de derivatización química, uso de columnas y detectores. Así mismo, se presentan metodologías de análisis que involucran otras técnicas más avanzadas siendo estas, una alternativa favorable para la detección de este herbicida. |

El uso excesivo y su impacto en el medio ambiente, ha promovido el análisis químico del Glifosato en el agua, el suelo y alimentos. Debido a la complejidad y características específicas de la molécula para ser analizada, es necesario implementar e introducir mejoras en las metodologías que permitan realizar procedimientos de detección a niveles de trazas. El Glifosato es un compuesto que no contiene una estructura química compleja, pero al tener cuatro grupos altamente polares, dificulta el análisis por métodos convencionales. Para la química, sigue siendo un desafío desarrollar técnicas que arrojen resultados confiables en tiempos cortos, teniendo en cuenta cada uno de los parámetros para que, en el momento de realizar la operación, el método elegido sea óptimo, confiable, eficaz y no se presenten errores en los procedimientos que pueden generar resultados incorrectos. Este trabajo se realiza a fin de recopilar las técnicas analíticas instrumentales usadas en la actualidad para la cuantificación y detección de Glifosato. Se describen los parámetros que deben ser relevantes para la determinación de Glifosato y su metabolito principal AMPA (ácido aminometilfosfónico) y procesos asociados a técnicas cromatográficas, que van desde rutas de degradación del contaminante, procedimientos de tratamiento de las muestras, reacciones de derivatización química, uso de columnas y detectores. Así mismo, se presentan metodologías de análisis que involucran otras técnicas más avanzadas siendo estas, una alternativa favorable para la detección de este herbicida.Glyphosate is the most widely used and marketed herbicide worldwide used primarily for weed control. Excessive use and its impact on the environment has promoted the chemical analysis of glyphosate in water, soil and food. Due to the complexity and specific characteristics of the molecule to be analyzed, it is necessary to implement and introduce improvements in the methodologies that allow detection procedures at trace levels. Glyphosate is a compound that does not contain a complex chemical structure, but having four highly polar groups makes analysis by conventional methods difficult. For chemistry, it is still a challenge to develop techniques that yield reliable results in short times, taking into account each of the parameters so that, at the time of performing the operation, the chosen method is optimal, reliable, efficient and not present Errors in procedures that may generate incorrect results. This work is done in order to compile the instrumental analytical techniques currently used for the quantification and detection of glyphosate. The parameters that should be relevant for the determination of glyphosate and its main metabolite AMPA (aminomethylphosphonic acid) and processes associated with chromatographic techniques, ranging from routes of contaminant degradation, sample treatment procedures, chemical derivatization reactions, are described. use of columns and detectors. Likewise, analysis methodologies are presented that involve other more advanced techniques, these being a favorable alternative for the detection of this herbicide.Maestría103application/pdfspa632 - Lesiones, enfermedades, plagas vegetales338 - ProducciónAMPAherbicidaglifosatocromatografíaderivatizaciónAMPAherbicidechromatographyderivatizationglyphosateMétodos analíticos para la determinación de Glifosato en matrices ambientalesDocumento de trabajoinfo:eu-repo/semantics/workingPaperinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/resource_type/c_8042http://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/WPBogotá - Ciencias - Maestría en Ciencias - QuímicaDepartamento de QuímicaUniversidad Nacional de Colombia - Sede BogotáH.
