TiO2 Nanovarillas Sensor Electroquímico Mercurio. Mercury (Hg) is one of the most toxic pollutants, it has become a serious threat to human health and the environment. Its exposure produces serious toxic effects in living beings, affecting the nervous, digestive and immune systems, and other parts of the organism. The environmental impact is significant and requires the attention of all the parties involved. For this reason, the development of analytical methods for the detection of low concentrations of Hg in different samples is a matter of scientific interest. Currently, the use of titanium oxide (TiO2) has revolutionized several fields generating new technological applications. The area of the sensors has not been alien to this revolution due to the properties of this material. In this research work, the development of a novel electrochemical sensor for the determination of ultratraces of mercury in water, from oriented nano-flowers of TiO2 is disclosed. The synthesis of the material was carried out on a carbon substrate (graphite) by the hydrothermal method. The determination of Hg2+ in water was made by cyclic voltammetry and differential pulse. The electrochemical tests of the sensor showed high sensitivity, selectivity and stability, as well as a wide range of detection in ppb. El mercurio (Hg) es uno de los contaminantes más tóxicos, se ha convertido en una amenaza seria para la salud humana y el ambiente. Su exposición, produce efectos tóxicos graves en seres vivos, afectando los sistemas: nervioso, digestivo e inmunitario, y otras partes del organismo. El impacto ambiental es significativo y requiere la atención de todas las partes involucradas. Por esta razón, el desarrollo de métodos analíticos para la detección de bajas concentraciones de Hg en diferentes muestras es un asunto de interés científico. Actualmente, el uso de óxido de titanio (TiO2) ha revolucionado diversos campos generando nuevas aplicaciones tecnológicas. El área de sensores no ha quedado ajena a esta revolución debido a las propiedades de este material. En este trabajo de investigación, se da a conocer el desarrollo de un sensor electroquímico novedoso para la determinación de ultratrazas de mercurio en agua, a partir de nano-flores de TiO2 orientados. La síntesis del material se realizó sobre un sustrato de carbono (grafito) por el método hidrotérmico. La determinación de Hg2+ en agua fue realizada mediante voltamperometría cíclica y de pulso diferencial. Las pruebas electroquímicas del sensor mostraron una sensibilidad, selectividad y estabilidad alta, así como un amplio intervalo de detección en ppb Universidad Autónoma de Baja California 2020-06-30 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Research article application/pdf text/html application/xml https://recit.uabc.mx/index.php/revista/article/view/3 10.37636/recit.v3296105 REVISTA DE CIENCIAS TECNOLÓGICAS; Vol. 3 No. 2 (2020): April-June; 96-105 REVISTA DE CIENCIAS TECNOLÓGICAS; Vol. 3 Núm. 2 (2020): Abril-Junio; 96-105 2594-1925 spa https://recit.uabc.mx/index.php/revista/article/view/3/12 https://recit.uabc.mx/index.php/revista/article/view/3/51 https://recit.uabc.mx/index.php/revista/article/view/3/165 Copyright (c) 2020 Juan José Hinostroza Mojarro, Mirza Mariela Ruiz Ramírez, Carolina Silva Carrillo, Rosa Maria Félix Navarro, Paul Antonio Valle Trujillo, Balter Trujillo Navarrete http://creativecommons.org/licenses/by/4.0
