This study aims to enhance local bentonite's effectiveness in removing methylene blue and procion deep red dyes from aqueous media through organic modification with cetyltrimethylammonium bromide surfactant. Raw modified bentonites were analyzed using XRF, XRD, FTIR, BET/BJH, DSC techniques. The bentonite showed a crystalline structure mesoporous morphology heterogeneous surface. Optimal adsorption conditions for MB dye 0.2 g adsorbent dose, 60 min contact time, mg/L initial concentration, pH 8, achieving maximum sorption capacity of 6.418 mg/g. For PDR dye, optimal 0.125 40 30 acidic pH, 8.503 Isotherm analysis indicated the Langmuir model best fits data, suggesting mono-layer process. Kinetic investigations revealed that follows pseudo-second-order model, indicating chemisorption mechanism. Thermodynamic results exothermic endothermic PDR. work highlights potential surfactant-modified as cost-effective sorbent treating polluted systems, effectively both cationic anionic dyes.
