(Texto tomado de la fuente)The treatment of wastewater from the tannery industry in the municipality of Belén, Nariño is of utmost importance for the communities of this region, mainly because in the leather transformation processes they use chromium, sodium and ammonium sulfates; and other reagents, which load the liquid waste with pollutants of difficult degradability; From there, approximately 322 3/ of effluents are discharged into natural water bodies, without any previous treatment. For this reason, in this work a heterogeneous adsorption and fenton technology was proposed as a treatment alternative, in terms of pollutant removal efficiency, operating costs and availability of raw materials. The document presents the synthesis and characterization process of a coffee husk adsorbent material and it impregnated with zero valent iron nanoparticles () for the adsorption of hexavalent chromium in solution ( ). In detail, a slight pretreatment with citric acid was explored to eliminate soluble compounds and improve the crystalline structure of the macromolecules of cellulose, hemicellulose and lignin of the coffee husk; likewise, the impregnated concentration in the biomass support was studied, in order to be characterized as a function of the zero charge point (), surface area (), surface morphology and Fourier transform infrared spectroscopy (). Furthermore, the synthesized materials were used to study the effects of adsorbent concentration, and contact time on the adsorption of () in solution. Once the optimal parameters were known, the studies of mass transfer, equilibrium and total chromium adsorption were studied in depth. The maximum adsorption capacities of () with an initial concentration of 5 / , were 3 / for natural coffee husk () and 2.01 / for coffee husk pretreated with citric acid (), however, for all the materials impregnated with it was approximately 9.9 / , loads reached at 120 , 130 and 2 , respectively. On the other hand, the best material impregnated with was selected for the heterogeneous fenton processes where the effects of 22/, and /22 were studied in the elimination of chemical oxygen demand (), total phenols () and with initial concentrations of 3277 2/, 200 / and 25 /, respectively, of a synthetic tannery wastewater. 95.24 % of , 97.54% of and 99.82% of () were removed. According to the results of this Master's thesis, it is recommended to evaluate the sustainability and potential application of the analyzed processes to the tannery industry currents.MaestríaMagíster en Ingeniería - Ingeniería QuímicaTratamiento de aguas residuales y aprovechamiento de residuos sólidosvi, 106 páginasapplication/pdfspaUniversidad Nacional de Colombia - Sede MedellínMedellín - Minas - Maestría en Ingeniería - Ingeniería QuímicaDepartamento de Procesos y EnergíaFacultad de MinasMedellínUniversidad Nacional de Colombia - Sede Medellín660 - Ingeniería químicaAguas residuales - TratamientoAdsorciónResiduos lignocelulósicosFenton heterogéneoTratamiento aguas residualesNanopartículas de hierroAdsorptionLignocellulosic wasteHeterogeneous fentonWastewater treatmentIron nanoparticlesEvaluación de la adsorción de cromo hexavalente y fenton heterogéneo para el tratamiento de aguas residuales sintéticas de curtiduría utilizando nanopartículas de hierro soportadas en cascarilla de café.Evaluation of the adsorption of hexavalent chromium and heterogeneous fenton for the treatment of synthetic tannery wastewater using iron nanoparticles supported on coffee huskTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMNariño, colombia[1] G.
