This study focuses on the development and evaluation of novel materials bentonite-CaO, magnetite bentonite-FeCl3, and magnetite bentonite-CaO/FeCl3 as potent adsorbents for the removal of methylene blue dyes from aqueous solutions. Batch adsorption test was conducted with variations of contact times and dye concentrations. The maximum sorption capacity reached 39 mg/g with Langmuir isotherm model (R2 =0.999) following the pseudo second-order kinetic model. The materials exhibited exceptional effectiveness, achieving a remarkable 99% reduction in methylene blue concentration within an astonishingly short 10-minute duration. Additionally, this study provides valuable insights into the potential applications of these modified adsorbents in environmental remediation, accompanied by practical recommendations for their utilization in various scenarios. © 2024 Global NEST Printed in Greece.
