Removal of chromium from effluents of tannery industry by electrodialysis
Descripción del Articulo
Chromium salts are chemical reagents widely used in the tannery industry because they are efficient for tanning animal skin, however, these salts are not completely fixed, so their remnants go to their effluents, seriously impacting the environment. The objective of this study was to remove chromium...

The objective of this study was to remove chromium (VI) and total chromium from a tannery effluent using electrodialysis, for this purpose, a sample of an effluent from a tannery pilot plant was characterized and then a synthetic solution was prepared based on this, using an industrial grade chrome salt for tannery, then the limiting current was determined and electrodialysis tests were carried out with the 80, 100 and 120% of the limiting current. The results showed that the highest percentage of extraction and the lowest electricity consumption was 80% of the limiting current.Las sales de cromo son reactivos químicos muy utilizados en la industria de curtiembre porque son eficientes para curtir la piel animal, sin embargo, estas sales no se fijan totalmente, por lo que, sus remanentes van a parar a los efluentes, impactando gravemente al medioambiente. El objetivo de este estudio fue remover el cromo (VI) y cromo total de un efluente de curtiembre utilizando electrodiálisis, para ello, se caracterizó una muestra de un efluente de una planta piloto de curtiembre y se preparó una solución sintética en base a ésta, utilizando una sal de cromo para curtiembres de grado industrial, luego, se determinó la corriente límite y se realizó pruebas de electrodiálisis con el 80, 100 y 120% de la corriente límite. Los resultados demostraron que el mayor porcentaje de extracción y el menor consumo de energía eléctrica fue al 80% de la corriente límite.Facultad de Ingeniería Industrial, Universidad Nacional Mayor de San Marcos2018-07-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/idata/article/view/1490810.15381/idata.v21i1.14908Industrial Data; Vol. 21 No. 1 (2018); 27-34Industrial Data; Vol. 21 Núm. 1 (2018); 27-341810-99931560-9146reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/idata/article/view/14908/13019Derechos de autor 2018 Alex Pilco Núñez, Félix Tinoco Angeles, Pedro Mamani Pichihua, Giovanni Yallico Acostahttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/149082021-07-14T16:25:53Z |
