Resumo: The present work aimed to evaluate the passion fruit residues (shells and seeds) as alternative adsorbents for the treatment of effluents contaminated by Red Quimicryl GRL dye, test the effect of ionic strength and pH on the efficiency of the adsorption process and finally check whether the desorption process is feasible. The adsorption process was carried out in a fixed bed column with the adsorbent in natura and treated with NaOH (sodium hydroxide). The effect of ionic strength was evaluated using together the dye solution NaCl (sodium chloride) at different concentrations, the pHs evaluated were 2, 5, 7 and 12, the desorption process was evaluated using HCl (hydrochloric acid) as an extracting solution. Thus, it was observed that the adsorption was favored by the biomass treated with NaOH, the effect of ionic strength influenced the adsorption process, and for the sample with 1.0 mol L-1 NaCl concentration, the adsorption process was advantageous, the pH directly influenced the process, and the higher the pH value the adsorption affinity increases, so the best pH tested was 12. The best biomass tested were passion fruit husks treated with NaOH with value of maximum adsorption capacity of 45.9 mg g-1 for the analyzed dye.

El proceso de adsorción se realizó en columna de lecho fijo con el adsorbente in natura y se trató con NaOH (hidróxido de sodio). El efecto de la fuerza iónica se evaluó utilizando en conjunto la solución de colorante NaCl (cloruro de sodio) a diferentes concentraciones, los pH evaluados fueron 2, 5, 7 y 12, el proceso de desorción se evaluó utilizando HCl (ácido clorhídrico) como solución extractora. Así, se observó que la adsorción fue favorecida por la biomasa tratada con NaOH, el efecto de la fuerza iónica influyó en el proceso de adsorción, y para la muestra con una concentración de NaCl 1.0 mol L-1, el proceso de adsorción fue ventajoso, el pH influyó directamente el proceso, y cuanto mayor es el valor de pH aumenta la afinidad de adsorción, por lo que el mejor pH probado fue 12. La mejor biomasa probada fueron las cáscaras de maracuyá tratadas con NaOH con un valor de capacidad máxima de adsorción de 45,9 mg g-1 para el colorante analizado.O presente trabalho teve como objetivo avaliar os resíduos de maracujá (cascas e sementes), como adsorventes alternativos para o tratamento de efluentes contaminados por corante Vermelho Quimicryl GRL, testar o efeito da força iônica e do pH na eficiência no processo de adsorção e por fim verificar se o processo de dessorção é viável. O processo de adsorção foi conduzido em coluna de leito fixo com o adsorvente in natura e tratado com NaOH (hidróxido de sódio). Foi avaliado o efeito da força iônica utilizando junto a solução do corante NaCl (cloreto de sódio) em diferentes concentrações, os pHs avaliados foram 2, 5, 7 e 12, o processo de dessorção foi avaliado utilizando como solução extratora HCl (ácido clorídrico). Com isso observou-se que a adsorção foi favorecida pela biomassa tratada com NaOH, o efeito da força iônica apresentou influência sobre o processo de adsorção, sendo que para a amostra com concentração de NaCl de 1,0 mol L-1 o processo de adsorção foi vantajosa, o pH influenciou de forma direta no processo, sendo que quanto maior o valor de pH a afinidade de adsorção aumenta, logo o melhor pH testado foi o de 12. A melhor biomassa testada foram as cascas de maracujá tratadas com NaOH com valor de capacidade máxima de adsorção de 45,9 mg g-1 para o corante analisado.Research, Society and Development2021-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2205910.33448/rsd-v10i14.22059Research, Society and Development; Vol. 10 No. 14; e266101422059Research, Society and Development; Vol. 10 Núm. 14; e266101422059Research, Society and Development; v. 10 n. 14; e2661014220592525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/22059/19572Copyright (c) 2021 Matheus Campos Castro; Eloize Silva Alves; Bruno Henrique Figueiredo Saqueti; Silvana Fernandes Montanherhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCastro, Matheus CamposAlves, Eloize SilvaSaqueti, Bruno Henrique FigueiredoMontanher, Silvana Fernandes 2021-12-04T11:48:39Zoai:ojs.pkp.sfu.ca:article/22059Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:41:19.724229Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
