| description |
The iron finishing industry in Mexico, employs sulfuric acid as a pickling agent to clean materials from scale, rust and dirt. Generaliy the industries do not treat or recycle the spent pickle liquors, and in most of the cases these acids are discharged directly to the drainage system acidifying the water streams. Alternatives of solution for this poliution problem were reviewed in the context of the Mexican industry,and a particular case was studied through the characterization of its spent pickle liquors. Proposed altematives are: neutralization, recycling and reuse (as reducing agent or saline-sodic soil reclamation agent) with no prior treatment of'the spent liquors. Recycling, either with H2SO4 or HC1, is considered as the optimal solution.Analysis of the spent pickle liquors of the case study indicate an acid concentration of 5.7% w/v* and an FeSO4•7H2O concentration of 27% w/v, with coefficiients of variation of 15 and 8% respectively. These contents are in the low range of those found for similar industries in developed countries. Other metals are present in the mg/L level: Mn, Na, Zn, Ca, K, Pb, Al, Cr, Ni and Mg. These metals should be considered as posible impurities in the end-products of the different proceses proposed. |

Pocas industrias, o quizá ninguna, reciclan los licores ácidos gastados. En la mayoría de los casos los descargan directamente al sistema de drenaje, con la consecuente acidificación de los cuerpos de agua receptores. Se revisaron diversas opciones para resolver este problema de contaminación en el contexto de la industria mexicana, mediante el estudio de una planta ubicada en el norte de la Ciudad de México. Se caracterizaron los desagües y los licores ácidos agotados y se propusieron las siguientes posibilidades de solución: la neutralización, el reciclado y/o el reuso directo ya sea como agente reductor o como recuperador de suelos salino-sódicos. Se consideró el reciclado como la soluciónóptima, tanto para plantas que utilizan H2SO4 como para aquellas que emplean HCl. Los anáiisis de los desagües indicaron que los siguientes pafámetros no cumplen con las normas mexicanas en vigor: pH, Fe, Zn, Mn, Pb y Cr. Los licores agotados mostraron concentraciones de H2S04 de 5.7% w/v* y de FeSO4•7H2O de 27% w/v*, con coeficientes de variación de 15 y 8% respectivamente. Estos contenidosse encuentran en la región baja de los intervalos informados en la literatura para industrias similares de países desarrollados. Además del hierro se determinaron: Mn, Na, Zn, Ca, K, Pb, Al, Cr, Ni y Mg; los cuales se encuentran en niveles de mg/L. La presencia de estos metales debe tomarse en cuenta en la implantación de cualquiera de las opciones propuestas, especialmente en el caso del reciclado, dado que pueden afectar la pureza del sulfato ferroso obtenido.Instituto de Ciencias de la Atmósfera, Universidad Nacional Autónoma de México2010-11-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionARTapplication/pdfhttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/21108Revista Internacional de Contaminación Ambiental; Vol. 6 Núm. 1 (1990); 33-54Revista Internacional de Contaminación Ambiental; Vol. 6 No. 1 (1990); 33-540188-4999reponame:Revista Internacional de Contaminación Ambientalinstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMspahttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/21108/19917Derechos de autor 2017 Revista Internacional de Contaminación Ambientalinfo:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/211082024-08-16T19:00:28Z |
