Resumo: | Currently, the state of the environment has demonstrated how important/vital it is to invest in technologies that work with systems that allow the reuse or disposal of products, since technologies are aimed at greater sustainability, either by reducing the load of pollutants and effluents or reusing these environmental liabilities in a practical application, generating savings. Thus, to mitigate the environmental impacts of the production of dyes and organic pigments from the chemical processes existing within the textile industry, between its molecule and its synthesis, this work sought to investigate the structural and morphological properties of the bioadsorbent, for application in adsorptive processes in the generation of a by-product and promoting the characterization of synthetic commercial dyes. As a bioadsorbent material, bacterial cellulose was used as an alternative method of removing dyes through adsorption, functioning as an absorbent capable of separating effectively due to its purity, elasticity, and biocompatibility. To analyze the adsorption parameters made by bacterial cellulose, the study methodology used was the UV/Vis analysis, ICP-OES, Principal Component Analysis (PCA) and Thermogravimetric Analysis (TGA). Thus, it was analyzed how much the use of recyclable technologies can promote a new way of using dyes, since nanofiltration can be contemplated by the membrane separation technique, which implies the promotion of sustainability. As results obtained, it was observed that the textile dyes, through the adsorption kinetics, presented a removal rate for C8 of approximately 16%, for C10. Adsorption kinetics can be well expressed by the pseudo-second order model, indicating the importance of chemical adsorption in the process. When carrying out the Thermogravimetric Analysis, it was noticed that the bacterial cellulose begins to lose its structural stability at 360ºC, reaching the apex at 555ºC, disappearing from the experiment, forming a subdye for reuse in a new dyeing process. In this way, it was concluded that with the amount of metals identified in the chemical composition of the dye, it is pointed out how important the use of bacterial cellulose was, also, in the promotion of disposal, since the metal develops resistance to the environment, and likewise would be a source of inorganic pollutant with high mobility and high toxicity. After analyzing the data, the result is the importance of Bacterial Cellulose (BC) in the removal of dyes in textile industrial effluents, as it degrades at a certain temperature and the dye becomes purified to be reused, thus protecting the environment and human health. |

Tese (Programa de Pós-Graduação em Química) - Universidade Federal Rural de Pernambuco, Recife.http://www.tede2.ufrpe.br:8080/tede2/handle/tede2/9667Currently, the state of the environment has demonstrated how important/vital it is to invest in technologies that work with systems that allow the reuse or disposal of products, since technologies are aimed at greater sustainability, either by reducing the load of pollutants and effluents or reusing these environmental liabilities in a practical application, generating savings.

Assim, para mitigar os impactos ambientais da produção de corantes e pigmentos orgânicos a partir dos processos químicos existentes dentro da indústria têxtil, entre sua molécula e sua síntese, este trabalho buscou investigar as propriedades estruturais e morfológicas do bioadsorvente, para aplicação em processos adsortivos na geração de um subproduto e promovendo a caracterização de corantes comerciais sintéticos. Enquanto material bioadsorvente utilizou-se da celulose bacteriana como um método alternativo de remoção de corantes por meio da adsorção, funcionando como um absorvente capaz de separar de forma eficaz devido a sua pureza, elasticidade e biocompatibilidade. Para analisar os parâmetros de adsorção feitos pela celulose bacteriana, a metodologia de estudo utilizada foi a análise de UV/Vis, ICP-OES, a Análise de Componentes Principais (PCA) e a Análise Termogravimétrica (TGA). Assim, analisou-se o quanto o uso de tecnologias recicláveis pode promover uma nova forma de utilização de corantes, uma vez que a nanofiltração pode ser contemplada pela técnica de separação por membrana, o que implica na promoção da sustentabilidade. Como resultados obtidos observou-se que os corantes têxteis por meio da cinética da adsorção apresentaram uma taxa de remoção para o C8 de aproximadamente 16%, para C10. A cinética de adsorção pode ser bem expressa pelo modelo de pseudo-segunda ordem, indicando a importância da adsorção química no processo. Ao realizar a Análise Termogravimétrica notou-se que a celulose bacteriana começa a perder estabilidade de sua estrutura aos 360ºC, atingindo o ápice aos 555ºC desaparecendo do experimento, formando um subcorante para reutilização em um novo processo de tingimento. Desta forma, concluí-se que com a quantidade de metais identificada na composição química do corante, aponta-se o quão importante foi o uso da celulose bacteriana, também, na promoção do descarte, uma vez que o metal desenvolve resistência ao meio ambiente, e da mesma forma seria uma fonte de poluente inorgânico com alta mobilidade e alta toxicidade. Após a análise dos dados, obtém-se como resultado a importância da Celulose Bacteriana (CB) na remoção de corantes em efluentes industriais têxteis, pois a mesma se degrada a certa temperatura e o corante torna-se purificado para ser reutilizado, protegendo assim o meio ambiente e a saúde humana.Submitted by Mario BC (mario@bc.ufrpe.br) on 2024-07-19T12:21:18Z No. of bitstreams: 1 Thais Jeruzza Maciel Povoas Souto.pdf: 3234191 bytes, checksum: 0b7af268299482ff9c284a8b82b08841 (MD5)Made available in DSpace on 2024-07-19T12:21:18Z (GMT).
