“…Adsorption isotherm is very important for describing how the adsorbate molecules interact with the adsorbent, and fully understanding the properties of interaction and distribution of adsorbate molecules between the gaseous and solid phases under equilibrium condition . In this study, 2 two‐parameter isotherm models of Langmuir and Freundlich were used to analyze the equilibrium isotherm data using the OriginPro 8 software.…”

“…Adsorption isotherm is very important for describing how the adsorbate molecules interact with the adsorbent, and fully understanding the properties of interaction and distribution of adsorbate molecules between the gaseous and solid phases under equilibrium condition. 56,57 In this study, 2 two-parameter isotherm models of Langmuir and The Langmuir isotherm assumes that monolayer adsorption happened at adsorption sites with homogenous energy levels; there is neither intermolecule interaction nor transmigration on the adsorption surface. 58 The Langmuir equation is represented as Equation (5).…”

“…In this work, the two-parameter models, namely the Langmuir, Freundlich, and Dubinin-Radushkevich (Table 6), were chosen to give an idea about the relationship between the distribution of the dye molecules in the liquid phase and in the solid surface at equilibrium (Jothirani et al 2016;Suganya et al 2017). The AB25 concentration ranges from 50 to 150 mg L −1 , while other parameters were preserved at optimum conditions.…”

“…Dyes are used as coloring agents in various industries such as the textile, leather, paper, plastic, cosmetics, printing, pharmaceuticals, and food (Anithaa et al 2016;Dashamiri et al 2017;Jothirani et al 2016). They generate colored wastewaters, depending on the fixation level of dye stuffs on the substrates, which change with the nature of the substance, the intensity of coloration, and the applied method (Amin 2009).…”

“…Corantes apresentam estruturas complexas, aromáticos tóxicos, não-biodegradáveis, cancerígenos. Estas águas residuais industriais são descartadas com grandes quantidades de corantes em fontes de água próximas as indústrias que, por sua vez, poluem os sistemas aquáticos inteirosJothirani et al, 2016).Os corantes reativos são aqueles que contêm um grupo eletrofílico (reativo) capaz de formar ligação covalente com grupos hidroxila das fibras celulósicas, com grupos amino, hidroxila e tióis das fibras protéicas e também com grupos amino das poliamidas, quando, contidos em águas residuais são muito difíceis de tratar, uma vez que são moléculas orgânicas recalcitrantes, resistentes à digestão aeróbia e são estáveis à luz, calor e agentes oxidantes. São diversas as técnicas que vem sendo aplicadas em escala industrial para o tratamento dessas águas residuais contaminadas com corantes, a citar, o carvão ativado,…”
