English title:	DEVELOPMENT OF A METHODOLOGY TO EVALUATE THE PHOTOCATALYTIC RESPONSE OF 〖TiO〗_2 COATINGS INCORPORATING HYDROXYAPATITE OBTAINED FROM FISH WASTE AND METAL NANOPARTICLES, IN THE REMEDIATION OF SURFACE WATERS IN TUMACO, COLOMBIA
Spanish title:	DESARROLLO DE UNA METODOLOG�A PARA EVALUAR LA RESPUESTA FOTOCATAL�TICA DE RECUBRIMIENTOS DE 〖TiO〗_2 INCORPORANDO HIDROXIAPATITA OBTENIDA DE RESIDUOS DE PESCADO Y NANOPART�CULAS MET�LICAS, EN LA REMEDIACI�N DE AGUAS SUPERFICIALES DE TUMACO, COLOMBIA
English abstract:	In this research project, the main objective that was proposed has been achieved, which consisted of developing a methodology to evaluate the photocatalytic response of 〖TiO〗_2 coatings that incorporate hydroxyapatite ions obtained from fish residues, together with the incorporation of metallic nanoparticles, for its application in the remediation of superficial bodies such as the Rosario river, in the region of Tumaco, Colombia. To achieve this goal, four specific objectives were carried out: First, 〖TiO〗_2 coatings were synthesized by plasma electrolytic oxidation, incorporating hydroxyapatite ions from fish waste and metal nanoparticles. Second, the morphological, structural and chemical properties of 〖TiO〗_2 coatings incorporating hydroxyapatite and metal nanoparticles were characterized. Third, simulations of the structural and energetic properties of 〖TiO〗_2 coatings incorporating hydroxyapatite ions and metal nanoparticles were performed. And finally, fourthly, the photocatalytic feasibility of hydroxyapatite-metal nanoparticles-〖TiO〗_2 systems was evaluated in the remediation of surface waters in the Tumaco region, specifically in the case of the Rosario River.

Para lograr este objetivo, se llevaron a cabo cuatro objetivos espec�ficos: en primer lugar, se sintetizaron recubrimientos de 〖TiO〗_2 por oxidaci�n electrol�tica por plasma, incorporando iones de hidroxiapatita proveniente de residuos de pescado y nanopart�culas met�licas. En segundo lugar, se caracterizaron las propiedades morfol�gicas, estructurales y qu�micas de los recubrimientos de 〖TiO〗_2 que incorporan hidroxiapatita y nanopart�culas met�licas. En tercer lugar, se realizaron simulaciones de las propiedades estructurales y energ�ticas de los recubrimientos de 〖TiO〗_2 que incorporan iones de hidroxiapatita y nanopart�culas met�licas. Y finalmente, en cuarto lugar, se evalu� la viabilidad fotocatal�tica de los sistemas de hidroxiapatita-nanopart�culas met�licas-〖TiO〗_2 en la remediaci�n de aguas superficiales de la regi�n de Tumaco, espec�ficamente en el caso del r�o Rosario.
