Efecto de la altura de empaquetamiento de un composito magnético en la remoción de cromo mediante una columna de adsorción

Abstract

At present, the tannery industry presents great problems, mainly in environmental and social aspects. For this reason, it is not only necessary to optimize its processes, but also in the manufacturing technology and the control of environmental impacts. For this reason, the objective of the present graduation work was to determine the effect of the packing height of a magnetic composite on the removal of chromium by means of an adsorption column. Using a methodology with a qualitative and quantitative approach, where the amount of chromium III present in the wastewater was quantified and the efficiency of the magnetic composites in terms of adsorption capacity was established. Qualitative aspects were also considered, such as the main vision of the project to minimize polluting components, the positive impact on the environment and the improvement of operating costs. An exploratory type design was used, since it focuses on the analysis, research and interpretation of different aspects and data obtained in the laboratories of the Faculty of Sciences of ESPOCH. As a result, a compound synthesized from magnetite together with cattail fiber was obtained and used as a composite for the retention of chromium III in the tanning industry. In addition, the pickling process showed the highest concentration of chromium oxide, with a value of 2258.46 mg/L. It was observed that the 9 cm column showed a higher efficiency in the retention of chromium III. Concluding that the packing height of a magnetic composite significantly influences the removal of chromium from wastewater, highlighting the efficiency of the composite in this treatment process. Recommending to employ the cattail magnetic composite as a bio adsorbent material to remove Cr^(+3)particles present in tannery treatments.
