Abstract
Developing efficient and eco-friendly adsorbents for removing dye from wastewater presents a significant challenge. In this study, by combining MgFe-hydrotalcite (MgFe-HT) with bamboo charcoal (BC) we report the synthesis of a composite material named BC-MgFe-HT to achieve rapid and effective adsorption of methylene blue (MB) dye. The novelty of our work lies in the distinctive intercalation arrangement of the MB dye post-adsorption within the BC-MgFe-HT layers, which was quantitatively measured and found to be at an intercalation angle of approximately 44.26° rather than the conventional vertical positioning. This unique phenomenon indicates a dynamic rearrangement of the composite structure upon MB adsorption, significantly enhancing its adsorption capacity and efficiency. Comprehensive characterization of the BC-MgFe-HT composite was performed using the following techniques…
