Item Obtención de carbón activado a partir de bagazo de caña para la descontaminación de tinidazol en aguas(Universidad Santiago de Cali, 2024) Walteros Ospina, Melisa Andrea; Ciro Monsalve, Yhors Alexander (Director); Rojas Camargo, John Jairo (Director)Pollution of water sources is a major problem worldwide. Activated carbon produced from agroindustrial waste has been used for the removal of emerging contaminants that affect water bodies. To address this problem, it was proposed to obtain activated carbon from sugarcane bagasse for the decontamination of tinidazole in water, through the carbonization of the materials at different times and temperatures. A positive result was obtained with the physical and chemical activation of the bagasse; however, the highest percentage of removal was obtained through chemical activation with phosphoric acid with a result of 78% removal of tinidazole. In addition, analyzes of non-sterile pharmaceutical products were carried out in this case, neither Pseudomonas aeruginosa nor Staphylococcus aureus grew in any of the materials. These results demonstrated the adsorption capacity of bagasse, which can generate alternatives for a second use of agroindustrial waste and can be used as bioremediation elements.
