“…Ribeiro et al[130] studied the physicochemical and morphological characterization of fish scales evaluating, also, their adsorption capacities for the removal of reactive blue 5G (RB5G) from aqueous solution. The fish scales of O.niloticus species were used as an adsorbent material.…”

Low-cost by-products from agricultural, household and industrial sectors have been recognized as a sustainable solution for wastewater treatment. They allow achieving the removal of pollutants from wastewater and at same time to contribute to the waste minimization, recovery and reuse. Despite numerous reviews have been published in the last few years, a direct comparison of data obtained using different sorbents is difficult nowadays because of inconsistencies in the data presentation. In this context, the aim of the study was to revise the current literature concerning the application of low-cost adsorbents for wastewater treatment highlighting, systematically, both adsorbents characteristics and adsorption capacities. For this scope, low-cost sorbents have been divided into the following five groups: (i) Agricultural and household wastes, (ii) industrial by-products, (iii) sludge, (iv) sea materials, (v) soil and ore materials and (vi) novel low-cost adsorbents. The affinity of sorbents in removing various pollutants, their applications on real wastewater, costs and considerations on their reuse after adsorption processes, has been discussed. Finally, in order to better highlights the affinity of sorbents for more pollutants (dyes, heavy metals, biorecalcitrant compounds, nitrogen and phosphate compounds), simple methodological tools such as "adsorbentspollutants" matrices have been proposed and applied. In this manner, the adsorbent candidates for

“…Therefore, at the higher aggregations states the dye diffusion into the porous structure would not be probable due to steric effects. In this sense, the steric limitations together with to the low porosity of adsorbent led to a negligible internal mass transfer resistance [9]. Additionally, the external mass transfer resistance, which depends on the hydrodynamics of the system [12], was negligible under the studied conditions of temperature and stirring speed.…”

“…However, the cost of the adsorbent may sometimes jeopardize the viability of this process, in this sense the replacement of traditional adsorbents (such as activated carbons, zeolites, among others) for less costly materials are the focus of several researchers [3,[5][6][7][8][9]. In this context, the sugarcane bagasse is a significant agro-industrial residue due to its abundance and availability, especially in tropical countries.…”

“…O modelo cinético de adsorção-dessorção de Langmuir foi escolhido para descrever os dados pelo fato do tamanho da molécula de corante RB5G (comprimento longitudinal = 22,02 Å, diâmetro médio = 10,68 Å) ser maior que o tamanho dos poros presentes no adsorvente (20,6 Å), conforme identificou RIBEIRO et al, (2015). Desta forma, acredita-se que a alta capacidade de adsorção da escama de peixe pelo corante RB5G esteja relacionado a adsorção na superfície do adsorvente.…”

RESUMOOs corantes estão presentes em altas concentrações no efluente têxtil e boa parte é descarregada em corpos hídricos devido a sua baixa biodegradabilidade e alta solubilidade. Desta forma, o efluente têxtil precisa ser tratado antes de despeja-lo no meio ambiente e o processo de adsorção pode ser um método eficiente, de fácil operação e de baixo custo, principalmente, se o adsorvente utilizado for subproduto industrial. Neste sentido, este trabalho tem como objetivo a obtenção da cinética e o equilíbrio de adsorção do corante reativo azul 5G (RB5G) utilizando escamas de peixe do gênero tilápia como adsorvente. Os experimentos de adsorção foram realizados em sistema fechado e batelada, em pH 2 e temperatura de 25ºC. Os dados de equilíbrio de adsorção foram modelados a partir da isoterma de Langmuir e foi obtida uma capacidade máxima de adsorção de 272,39 mg/g. Os dados da cinética de adsorção foram obtidos nas concentrações iniciais de RB5G de 25, 50, 100, 150 e 200 mg L -1 , respectivamente e o tempo de equilíbrio alcançado foi de 72 horas. A cinética de adsorção foi descrita pelo modelo de adsorção-dessorção de Langmuir, o qual se ajustou bem aos dados experimentais. Desta forma, a remoção do corante RB5G pela escama de peixe se mostrou eficiente, a qual apresentou capacidade de adsorção elevada. Os modelos ajustados aos dados cinéticos e de equilíbrio de adsorção descreveram bem os dados experimentais, assim, as informações fornecidas pelos modelos podem ser utilizadas no projeto deste processo em escala piloto.
