Resumo: Contamination of effluents often occurs due to improper disposal of textile dyes or their by-products. These can often be carcinogenic and/or mutagenic to the biome. Given the above, the need for effective methods for treating effluents is clear. This treatment occurs by biological, physical, and/or chemical processes. Regarding chemical processes, heterogeneous photocatalysis stands out, mainly because it guarantees an effective degradation of contaminants. In this sense, mixed metal oxides, act as photocatalysts and constitute structures capable of producing a large family of solids with physical properties suitable for the degradation of many pollutants. Modified ABO3 perovskites, as in the case of the SrZrxSn1-xO3 semiconductor system, are effective in the degradation of textile dyes in effluents. The present work aimed to use the Box-Behnken model to evaluate the performance of the oxides resulting from the structural modifications of the perovskite SrZrxSn1-xO3 system, concerning the discoloration of the golden yellow dye remazol. The synthesized oxides were characterized by instrumental techniques and a Box-Behnken 34 project was developed. From this, the influence of some factors such as structural modification, oxide mass, exposure time, and the number of UVC lamps was evaluated. The discoloration of the dye was monitored from the attenuation of the absorbance at the wavelength 411 nm. According to the results obtained, the highest percentage of discoloration was obtained using the modified oxide SrZr0,25Sn0,75O3 for an approximate time of 6 hours in contact with 1 UVC lamp.

A menudo, estos pueden ser cancerígenos y / o mutagénicos. Dado lo anterior, es clara la necesidad de métodos efectivos para el tratamiento de efluentes. Este tratamiento ocurre por procesos biológicos, físicos y / o químicos. En cuanto a los procesos químicos, destaca la fotocatálisis heterogénea, principalmente porque garantiza una degradación eficaz de los contaminantes. En este sentido, los óxidos metálicos mixtos, actúan como fotocatalizadores y constituyen estructuras capaces de producir una gran familia de sólidos con propiedades físicas aptas para la degradación de contaminantes. Las perovskitas como en el caso del sistema semiconductor SrZrxSn1-xO3, son eficaces en la degradación de los tintes textiles en los efluentes. El presente trabajo tuvo como objetivo utilizar el modelo de Box-Behnken para evaluar el comportamiento de los óxidos resultantes de las modificaciones estructurales del sistema SrZrxSn1-xO3, en relación con la decoloración del tinte amarillo dorado remazol. Los óxidos sintetizados se caracterizaron mediante técnicas instrumentales y se desarrolló un proyecto Box-Behnken 34. A partir de esto, se evaluó la influencia de factores como la modificación estructural, la masa de óxido, el tiempo de exposición y el número de lámparas UVC. La decoloración del tinte se controló a partir de la atenuación de la absorbancia a la 411 nm. Según los resultados, el mayor porcentaje de decoloración se obtuvo utilizando el óxido SrZr0.25Sn0.75O3 durante un tiempo aproximado de 6 horas en contacto con 1 lámpara UVC.A contaminação de efluentes muitas vezes ocorre pelo descarte inadequado de corantes têxteis ou seus subprodutos.

A partir deste a influência de alguns fatores como modificação estrutural, massa de óxido, tempo de exposição e o número de lâmpadas UVC foram avaliados. A descoloração do corante monitorada a partir da à atenuação da absorbância no comprimento de onda 411 nm. De acordo com os resultados obtidos o maior percentual de descoloração foi obtido utilizando o óxido modificado SrZr0.25Sn0.75O3 por um tempo aproximado 6 horas em contato com 1 lâmpada UVC.Research, Society and Development2021-02-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1232810.33448/rsd-v10i2.12328Research, Society and Development; Vol. 10 No. 2; e48610212328Research, Society and Development; Vol. 10 Núm. 2; e48610212328Research, Society and Development; v. 10 n. 2; e486102123282525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/12328/11516Copyright (c) 2021 Yohanna Ribeiro Klafke; Mayara Macedo da Mata; Ieda Maria Garcia dos Santos; Mary Cristina Ferreira Alves; Simone da Silva Simõeshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessKlafke, Yohanna Ribeiro Mata, Mayara Macedo da Santos, Ieda Maria Garcia dos Alves, Mary Cristina Ferreira Simões, Simone da Silva 2021-03-02T09:32:39Zoai:ojs.pkp.sfu.ca:article/12328Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:33:56.059025Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
