Evaluating sustainable agricultural waste biomass for methylene blue adsorption in wastewater treatment: A state-of-the-art review

The presence of Methylene blue (MB) dye in aquatic environments is a significant concern due to its extensive industrial usage, particularly in the textile industry. This article discusses different methods for removing pollutants from wastewater, specifically focusing on adsorption techniques that utilize agricultural waste as eco-friendly adsorbents. It provides a comprehensive review of the activation chemicals, methods, and various characterization techniques such as FTIR, BET, SEM-EDX, and bio-sorbent materials. In our study, we have employed various models such as the isotherm model, kinetic model, and thermodynamic parameters to analyze the data. The study emphasizes the importance of conducting further research to enhance treatment methods and minimize the negative impacts of MB contamination. It also identifies areas where the current understanding is lacking. This review contributes to the development of cost-effective and feasible technology for addressing the global issue of artificial dye pollution in aquatic environments, thereby promoting environmentally friendly wastewater treatment methods.
