| Resumo: | The incorrect disposal of organic dyes in water bodies can result in irreversible environmental damage. In this scenario, adsorption has been used as a simple and economically viable technique for water decontamination, as it allows the use of different types of waste, including sugarcane bagasse, as an adsorbent material. Therefore, this study brings information from the literature on the adsorption process of methylene blue, using sugarcane bagasse as an adsorbent matrix, which showed a high adsorption capacity, especially when subjected to physical-chemical treatments, or even in natura. . The study revealed that high concentrations of adsorbate and adsorbent favor the removal rate (%) and that the use of basic pH benefits the adsorption kinetics, which follows a pseudo second-order model. The Langmuir isortherm was, mostly, the most adequate model, corroborating that the interaction between adsorbate and adsorbent occurs in monolayers and is of the chemical type. |
