La presente investigación plantea la producción de un material compuesto basado en las nanohojas de nitruro de carbono grafítico (g-CN) recubiertas con nanopartículas de ferrita de cobalto, CoFe2O4 (CF), y embebidas en quitosano entrecruzado, con la finalidad de aplicarlo en procesos de inactivación fotocatalítica de cuerpos de agua contaminados con bacterias, así como en la degradación oxidativa de ibuprofeno, utilizando una fuente de radiación de 400 nm y 10 W.
El g-CN fue obtenido por descomposición térmica de melamina o urea y la CF a partir de FeCl2.4H2O y Co(NO3)2.6H2O en medio alcalino y en presencia de g-CN. El material obtenido fue dispersado en solución acética de quitosano y se formaron perlas por goteo sobre solución de NaOH 2M. Los materiales sintetizados fueron caracterizados por difracción de Rayos X (DRX), espectroscopía infrarroja con transformada de Fourier (FTIR) y microscopía electrónica de barrido por emisión de campo (FESEM).
El compósito final (quitosano/1CF5g-CN_m) alcanzó un valor cercano al 51% de eficiencia de degradación fotocatalítica oxidativa de ibuprofeno en solución acuosa. En cuanto a las pruebas de inactivación bacteriana de Escherichia coli, se alcanzó una disminución de hasta dos órdenes de magnitud, correspondiente a un 21% al final del proceso fotocatalítico.
This research proposes the production of a composite material consisting of nanosheets of graphitic carbon nitride (g-CN) coated with cobalt ferrite nanoparticles (CF) and embedded in cross-linked chitosan. The aim of the work was to apply this material in photocatalytic inactivation processes of water bodies polluted with bacteria, as well as in the oxidative degradation of ibuprofen, using a 400 nm and 10 W radiation source.
The g-CN was obtained through the thermal decomposition of melamine or urea, and CF was produced from FeCl2.4H2O and Co(NO3)2.6H2O in an alkaline medium in the presence of g-CN nanosheets. The resulting material was dispersed in an acetic chitosan solution, forming beads by dripping the mixture onto 2M NaOH solution. The synthesized materials were characterized using X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Field Emission Scanning Electron Microscopy (FESEM).
The final composite (chitosan/1CF5g-CN_m) achieved a yield close to 51% for the oxidative photocatalytic degradation efficiency of ibuprofen in aqueous solution. Regarding bacterial inactivation tests of Escherichia coli, a reduction of up to two orders of magnitude, corresponding to 21% at the end of the photocatalytic process, was attained.

O g-CN foi obtido por decomposição térmica de melamina ou ureia, e a CF a partir de FeCl2.4H2O e Co(NO3)2.6H2O em meio alcalino na presença de g-CN. O material obtido foi disperso em solução acética de quitosano, e pérolas foram formadas por gotejamento sobre uma solução de NaOH 2M. Os materiais sintetizados foram caracterizados por difração de raios-X (DRX), espectroscopia infravermelha com transformada de Fourier (FTIR) e microscopia eletrônica de varredura por emissão de campo (FESEM).
O compósito final (quitosano/1CF5g-CN_m) atingiu um valor próximo a 51% de eficiência na degradação fotocatalítica oxidativa de ibuprofeno em solução aquosa. Quanto aos testes de inativação bacteriana de Escherichia coli, observou-se uma redução de até dois ordens de magnitude, correspondendo a 21% no final do processo fotocatalítico.
