Methyl Violet (MV) removal from aqueous solutions is studied using an Algerian Bentonite sample as a low-cost adsorbent. SEM-EDX, X-ray diffraction, and chemical composition characterized the adsorbent material. The modeling optimization study of MV adsorption artificial neural network (ANN) response surface methodology (RSM) were also examined. effects pH, contact time, dye concentration, temperature are all considered. kinetics results adjusted to best fit pseudo-second-order model. Langmuir-Freundlich Langmuir models well describe experimental data with capacity 472 mg g−1. calculated thermodynamic demonstrates that spontaneous endothermic. Desorption studies methanol indicate could successfully retain MV, even after five cycles. statistical physics theory indicates non-parallel orientation molecule's adsorption. energies varied 13.99 17.60 kJ mol−1, revealing physical systems. From these results, it can be considered raw bentonite tested herein effective in removing may used alternative high-cost commercial adsorbents.
