The carbon quantum dots were characterized using Fourier-transform infrared spectroscopy, Raman spectroscopy, X-ray diffraction, UV-Vis spectroscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy, revealing their physicochemical properties, morphology, chemical composition, and crystalline structure the efficacy of carbon quantum dots in degrading the dyes was assessed via ultraviolet visible spectroscopy, demonstrating their ability to reduce dye concentrations. UAN Proyectos de ciencia, tecnología, innovación y creación artística Este trabajo propone la síntesis de puntos cuánticos de carbono mediante irradiación de microondas y su aplicación en la degradación de los colorantes Safranina, Verde de malaquita y Rojo Congo. Los puntos cuánticos de carbono se caracterizaron mediante difracción de rayos X, espectroscopía infrarroja por transformada de Fourier, espectroscopía Raman, espectroscopía ultravioleta-visible, microscopía electrónica de transmisión de barrido y espectroscopía de dispersión de energía de rayos X, evidenciando las propiedades fisicoquímicas, la morfología, la composición química y su estructura cristalina. final Bioquímico(a) Pregrado Presencial Investigación 2024-10-07T21:58:37Z 2024-10-07T21:58:37Z 2024-10-07 Estudio descriptivo Versión original del autor, Borrador, Manuscrito http://purl.org/coar/resource_type/c_7a1f http://purl.org/redcol/resource_type/PID http://purl.org/coar/version/c_b1a7d7d4d402bcce Tesis/Trabajo de grado - Monografía - Pregrado https://repositorio.uan.edu.co/handle/123456789/10298 Español Acceso a solo metadatos Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0) https://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/closedAccess http://purl.org/coar/access_right/c_16ec pdf application/pdf application/pdf application/pdf Universidad Antonio Nariño Bioquímica Facultad de Ciencias Bogotá - Circunvalar reponame:Repositorio Institucional UAN Başoğlu, A., Ocak, Ü., & Gümrükçüoğlu, A.
