Resumo: | Metal alloys are the most used products in day-to-day tasks, and thousands of tons are discarded into the environment daily. By studying metal corrosion processes, it is possible to propose applications for unused metallic materials, using oxidation in an acid medium, and generating hydrogen. With this, the objective of this work is to evaluate the acid corrosion of metals, reused, for the production of hydrogen. The methodology used was corrosion carried out with steel and gray cast iron, from automotive scrap, varying and combining the metallic material, the types of acids (Sulfuric and Hydrochloric) and the reaction time, building the curve of material corrosion. To quantify Fe levels, flame atomic absorption spectrometry was used. The results showed the influence of acids and metals, with different properties and chemical compositions, on the corrosion rate and consequently on the loss of material. Based on the literature, the possible factors that are significant in the reaction that caused unexpected behaviors to occur in the results, such as the greater loss of mass of the metal when immersed in acid with lower molarity, were justified. As final considerations, it was found that it is possible to proceed with research aimed at the production of hydrogen from the corrosion of residual metals, in order to minimize environmental problems, generating a new source of energy. |

Mediante el estudio de los procesos de corrosión de los metales, es posible proponer aplicaciones para materiales metálicos en desuso, utilizando la oxidación en medio ácido y generando hidrógeno. Con esto, el objetivo de este trabajo es evaluar la corrosión ácida de metales, reutilizados, para la producción de hidrógeno. La metodología utilizada fue la corrosión realizada con acero y fundición gris, a partir de chatarra automotriz, variando y combinando el material metálico, los tipos de ácidos (Sulfúrico y Clorhídrico) y el tiempo de reacción, construyendo la curva de corrosión del material. Para cuantificar los niveles de Fe se utilizó espectrometría de absorción atómica de llama. Los resultados mostraron la influencia de ácidos y metales, con diferentes propiedades y composiciones químicas, sobre la velocidad de corrosión y consecuentemente sobre la pérdida de material. Con base en la literatura, se justificaron los posibles factores significativos en la reacción que provocaron comportamientos inesperados en los resultados, como la mayor pérdida de masa del metal al ser sumergido en ácido de menor molaridad. Como consideraciones finales, se encontró que es posible proceder con investigaciones encaminadas a la producción de hidrógeno a partir de la corrosión de metales residuales, con el fin de minimizar los problemas ambientales, generando una nueva fuente de energía.As ligas metálicas são os produtos mais utilizados nas tarefas do dia-a-dia, sendo que diariamente são descartados milhares de toneladas no meio ambiente. Pelo estudo de processos de corrosão de metais, é possível propor aplicações para materiais metálicos inutilizados, empregando-se oxidação em meio ácido, e gerando-se hidrogênio. Com isso, o objetivo desse trabalho é avaliar a corrosão ácida de metais, reaproveitados, para a produção de hidrogênio. A metodologia utilizada foi a corrosão realizada com aço e ferro fundido cinzento, provenientes de sucatas automotivas, variando-se e combinando-se o material metálico, os tipos de ácidos (Sulfúrico e Clorídrico) e o tempo de reação, construindo-se a curva de corrosão do material. Para a quantificação dos teores de Fe, foi empregada a espectrometria de absorção atômica com chama. Nos resultados foi apresentada a influência de ácidos e metais, com propriedades e composições químicas distintas, na velocidade de corrosão e consequentemente na perda de material. Foram justificados com base na literatura, os possíveis fatores que são significativos na reação que fizeram com que ocorressem comportamentos inesperados nos resultados, como a maior perda de massa do metal quando imerso em ácido com menor molaridade. Como considerações finais, verificou-se que é possível prosseguir com pesquisas que visem a produção de hidrogênio a partir da corrosão de metais residuais, de forma a minimizar problemas ambientais, gerando uma nova fonte de energia.Research, Society and Development2022-03-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2705410.33448/rsd-v11i4.27054Research, Society and Development; Vol. 11 No. 4; e14511427054Research, Society and Development; Vol. 11 Núm. 4; e14511427054Research, Society and Development; v. 11 n. 4; e145114270542525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/27054/23765Copyright (c) 2022 Pâmella Oliveira Bernardo Ferreira; Tatiane Carvalho Maeda; Alexandre de Faria Lima; Geoffroy Roger Pointer Malpass ; Sandra Cristina Dantashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFerreira, Pâmella Oliveira BernardoMaeda, Tatiane CarvalhoLima, Alexandre de FariaMalpass , Geoffroy Roger Pointer Dantas, Sandra Cristina2022-03-27T17:17:09Zoai:ojs.pkp.sfu.ca:article/27054Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:54.131839Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
