Abstract: RESUMOAs indústrias têxteis estão crescendo cada vez mais, hoje em dia, cerca de 10.000 tipos diferentes de corantes e pigmentos são utilizados industrialmente e a estimativa de corantes descartados junto aos despejos dos efluentes chega a 1,0x10 6 kg/ano. A remoção da cor pela adsorção é uma tecnologia relativamente nova e tem demonstrado bastante eficiência, visto que é uma tecnologia barata e de simples operação. No entanto, devido ao elevado custo dos adsorventes comerciais, materiais alternativos que unam… Show more

“…However, some studies have achieved higher efficiencies in MB removal, such as: Dotto et al (2015), with a 85% removal of the dye with shrimp residue; Ahmad and Ansari (2021), who achieved results above 88% in neutral pH, with the use of hybrid clay with modified nanocompost of chitosan; Ma et al (2016), which reached up to 90% of MB removal by using foam composed of graphene oxide/chitin; Mabel et al (2019), with an efficiency of 90% of adsorption with crustacean chitin; Lima et al (2006), with a 97% MB removal with the use of activated carbon; Jorge et al (2015), which also removed 97% of the initial concentration of MB, but with the use of sugarcane bagasse; Silva et al (2018), with a removal efficiency of 99% of MB with the use of activated charcoal of ryegrass straw. Jawad et al (2020) obtained 90% MB removal efficiency, differing in the methodology applied to the research in time and rotation parameters, from 180 minutes at 110 RPM.…”

“…According to Bailey et al (1999Bailey et al ( , p. 2469, the adsorbent must have "little processing, be of an abundant nature, or a by-product or material of waste from another industry. " Potential adsorbents are numerous organic residues, such as sugarcane residues (Jorge et al, 2015), ryegrass straw (Silva et al, 2018), fly ash (Cunico et al, 2015), green coconut (Oliveira et al, 2018), pine and bamboo sawdust (Müller et al, 2019). Many research on adsorption of dyes from crustacean residues (Dotto et al, 2011;Labidi et al, 2019;Mabel et al, 2019) refer to the use of chitin.…”

“…O valor do parâmetro n>1 indica que a superfície do biossorvente é altamente heterogênea e assim ocorre a formação de mais de uma camada de adsorbato no adsorvente, o que caracteriza uma cooperatividade positiva, em a adsorção em cada camada contribui para a adsorção das camadas seguintes por intermédio de interações laterais das moléculas (Praus e Turicová, 2007;Sotiles, 2017). Isoterma de Sips geralmente se ajusta bem em processos de biossorção, como encontrado por Jorge et al (2015), que estudou a adsorção de corante azul de metileno em bagaço de cana.…”

“…Na literatura encontram-se vários trabalhos usando biomassas na adsorção de corantes de efluentes têxteis (Ho & Mckay, 1998;Zhang et al, 2011;Jorge et al, 2015;Sotiles, 2017), de metais pesados (Colombo, 2013;Silva, 2014), gases (Ursueguía et al, 2020;Wang et al, 2020), compostos orgânicos (Corseuil, 1992;Santos et al, 2003), dentre outros. O tema selecionado pelos alunos foi a adsorção empregando biomassa, para solucionar um problema de derramamento de gasolina ocorrido em Bogotá, Colômbia.…”

“…Vários materiais adsorventes estão sendo utilizados para a remoção de vários tipos contaminantes, incluindo os efluentes têxteis (Guimarães et al, 2020). São exemplos de biosorventes: casca de coco (Jawad et al, 2020), casca de frutas cítricas (Aichour et al, 2019); bagaço de cana de açúcar (Jorge et al, 2015;Buthiyappan et al, 2019), resíduo de algodão (Charola et al, 2018), casca de arroz (Salem et al, 2018) e palha de milho (Ismail eta al., 2019), pó de serragem (Müller, 2016;Agarwal et al, 2016), casca de banana (Almeida & Santos, 2020) entre diversos outros trabalhos de pesquisa.…”
