Resumo: Heavy metal pollution is an serious environmental problem because they have toxic effects on living organisms. In recent years, the use of microbial biosorbents to remove heavy metal pollution have studied.  Many biological materials are used to remove copper ions. In this study, the biosorption capacity of lyophilized Pantoea agglomerans for Cu (II) ions were investigated under various conditions (initial pH, contact time, initial heavy metals ion concentration). The monocomponent biosorption data have been analyzed using isotherm (Freundlich and Langmuir) and kinetic models. The highest copper uptake capacity of the biomass was obtained at the initial copper concentration of 250 mgL-1 at pH 5.0 and contact time 90th minute. The equilibrium data correlated well with the Langmuir and Freundlich model. It was found that the pseudo-second-order kinetic model fitted the experimentally obtained data. Liyofilized P. agglomerans biomass appears to be an inexpensive and efficient biosorbent for the removal of Cu (II) from aqueous solutions.

Estudos recentes têm focado no uso de biossorventes potenciais de base microbiana para remoção de metais pesados. Muitos materiais biológicos para a remoção de íons de cobre já foram empregados. Neste estudo, a capacidade de biossorção e capacidade de Pantoea aglomerans liofilizados para íons Cu (II) foram investigados sob várias condições. Sua capacidade de absorção de íons cobre foi determinada em função do pH inicial, tempo de contato, concentração inicial de íons íons Cu (II). Os dados de biossorção de monocomponentes foram analisados ​​usando os modelos isotérmicos de Freundlich e Langmuir. Foram estudados os modelos cinéticos de biossorção de íons de metais pesados ​​nos P. aglomerados liofilizados. O pH do cobre mais favorável para remoção foi determinado como 5,0. A maior capacidade de absorção de  Cu(II) da biomassa foi obtida na concentração inicial de cobre de 250 mgL-1. Os dados de equilíbrio se correlacionaram bem com o modelo de Langmuir e Freundlich. Verificou-se que o modelo cinético de pseudo-segunda ordem se ajustava aos dados obtidos experimentalmente. A biomassa liofilizada de P. agglomerans é um biossorvente barato e os resultados indicaram que ele é eficiente… eficiente para a remoção de Cu(II) de soluções aquosas.Universidade Federal de Campina Grande - UFCG2022-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/61910.22571/2526-4338619Acta Brasiliensis; Vol 6 No 3 (2022): Acta Brasiliensis; 89-94Acta Brasiliensis; Vol 6 No 3 (2022): Acta Brasiliensis; 89-94Acta Brasiliensis; Vol 6 No 3 (2022): Acta Brasiliensis; 89-942526-43382526-432Xreponame:Acta Brasiliensis (Online)instname:Universidade Federal de Campina Grande (UFCG)instacron:UFCGenghttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/619/152Copyright (c) 2022 Acta Brasiliensisinfo:eu-repo/semantics/openAccessKıvanç, MerihOkus, Fatma Günaydın2022-09-30T22:13:56Zoai:ActaBra.revistas.ufcg.edu.br:article/619Revistahttp://revistas.ufcg.edu.br/ActaBraPUBhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/oaiactabrasiliensis@gmail.com || actabrasiliensis@gmail.com2526-432X2526-4338opendoar:2022-09-30T22:13:56Acta Brasiliensis (Online) - Universidade Federal de Campina Grande (UFCG)false
