“…In addition to biomass from microorganisms, as indicated above, a large number of materials have been evaluated as biosorbents to eliminate different pollutants, among the most recent are: agro-industrial waste materials [14], sludge [15,16], polysaccharides [17], plant-derived materials [18][19][20] and biopolymers [21]; although it is necessary to indicate that throughout the years of development of biosorption, a large number of biological materials of very diverse origin have been evaluated as possible biosorbents [22,23]. Many of these materials are considered as waste: for this reason, the use of these materials as biosorbents has a double advantage, on the one hand, a waste is used for an application, and therefore, its waste is reduced; on the other hand, this material is used to eliminate pollution with a possible low cost.…”

Biosorption is a variant of sorption techniques in which the sorbent is a material of biological origin. This technique is considered to be low cost and environmentally friendly, and it can be used to remove pollutants from aqueous solutions. The objective of this review is to report on the most significant recent works and most recent advances that have occurred in the last couple of years (2019–2020) in the field of biosorption. Biosorption of metals and organic compounds (dyes, antibiotics and other emerging contaminants) is considered in this review. In addition, the use and possibilities of different forms of biomass (live or dead, modified or immobilized) are also considered.

“…Obviously, this pH range cannot be used with living biomass; however, the biological activity of this type of biomass can compensate for this inconvenience, especially using resistant strains [85]. This behavior can be applied to other metals such as dysprosium [88], arsenic [89] or tungsten [20].…”

“…Pelo modelo de Freudlich, a adsorção acontece em multicamadas, fazendo com que fique retida uma maior quantidade de poluente na superfície celular. MAHMOUDI et al [95] testou a remoção do poluente com o material sintetizado óxido de grafeno coberto por sílica, o qual utilizou no seu método de preparação o reagente com grau de toxicidade permanganato de potássio. O teste experimental apresentou o valor máximo na capacidade de remoção igual a 42mg g -1 , que é inferior ao do estudo apresentado na Tabela 5.…”

RESUMO Métodos convencionais de tratamento de águas residuais apresentam determinadas limitações, como a baixa remoção de poluentes orgânicos refratários, necessidade de grandes áreas de instalação e os elevados custos para implementação e operação. Assim, processos alternativos vêm sendo aplicados para o tratamento de água residuais, como a adsorção, pela sua versatilidade e a possibilidade de utilização de materiais alternativos (biossorventes). O processo de biossorção é considerado uma alternativa biotecnológica para o tratamento de águas residuais, por meio da utilização dos biossorventes, como resíduos agroindustriais. Neste contexto, o presente trabalho tem como objetivo apresentar uma revisão bibliográfica de caráter exploratória e qualitativa, relacionando a aplicação do processo de biossorção na remoção de contaminantes em águas residuais. Assim, a maioria das biomassas vivas e mortas demonstraram ótimos resultados na captação de poluentes em meio aquoso, sendo promissoras no tratamento de águas residuais industriais. Além disso, resíduos agroindustriais que se acumulam por não apresentarem o correto gerenciamento, também foram testados para metais pesados e em sua maioria tiveram bom desempenho de capacidade biossortiva. A biomassa de natureza microbial apresentou menores valores de capacidade adsortiva para a remoção de poluentes, já que foi necessário o controle de nutrientes e das variáveis necessárias à sobrevivência das células. É importante destacar a maior complexidade de remoção dos compostos orgânicos, visto que apresentam em suas estruturas química grupos funcionais específico de natureza iônica diferente, dificultando a interação entre biossorvente e poluente orgânico. Por conseguinte, foi possível identificar a versatilidade do processo de biossorção, bem como a possibilidade de utilização de materiais alternativos.

“…However, not much information is available about tungsten removal from aqueous solutions through sorption. The sorbents for the removal of tungsten that have been described in the literature include biosorbent [ 23 , 24 ], biopolymer-coated clay [ 25 ], carbon cloth [ 26 ], fly ash [ 27 ], boehmite [ 28 ], nanocrystalline iowaite [ 29 ], and carbon nanotubes [ 30 ]. Of them, iron-bearing sorbents have been given priority in view of the fact that iron is able to effectively complex with tungstate species.…”

“…Of them, iron-bearing sorbents have been given priority in view of the fact that iron is able to effectively complex with tungstate species. For example, garlic peel loaded with Fe(III) possessed a tungsten sorption capacity of 91.5 mg/g, much higher than that of garlic peel with either Te(IV) or Ce(III) being loaded [ 24 ]. Ogata et al [ 31 ] also observed that a higher amount of tungsten was adsorbed onto the zeolite fly ash surface than onto the fly ash surface.…”

High concentrations of tungstate in aqueous systems pose a severe threat to the environment and human health. This study explored the potential of iron-based LDHs to remove tungstate from water. To improve its tungstate uptake capacity, environment-friendly L-asparagine was used to delaminate iron-based LDH synthesized via a coprecipitation method. The successful delamination was proved by AFM, revealing that the thickness of the obtained nanoparticles was approximately 1–2 times that of a single LDH layer. XRD, TEM, and XPS analyses confirmed that the delaminated LDHs were amorphous and ultrathin and had surface defects within their nanosheets that acted as active sites, leading to a very fast tungstate sorption rate and superior tungstate uptake capacity. Notably, the original layered structure of the L-asparagine-treated LDH was recovered upon its reaction with tungstate-bearing solutions, and therefore, the high availability of aqueous tungstate to the interlayer regions during the structural restoration of the delaminated iron-based LDH contributed to its excellent capability of tungstate removal as well. In addition, the tungstate uptake by the delaminated iron-based LDH was not affected substantially by the presence of coexisting anions, implying that the strong inner-sphere complexation between the tungstate and LDH layers with defects (i.e., Fe-O bonds) was the primary mechanism responsible for the tungstate removal. The delamination process described in this paper was validated to be an effective way to enhance the immobilization of tungstate by iron-based LDHs without inducing secondary pollutions, and delaminated iron-based LDHs are promising to be used extensively in the practice of treating tungstate-rich waters.
