This study investigates the adsorption of Methylene Blue (MB) and Methyl Orange (MO) onto Fika bentonite clay. Batch experiments evaluated the effects of contact time, adsorbent dose, initial concentration, and pH. The clay achieved over 99% removal for both dyes. Equilibrium was reached within 20 min for MB and 60 min for MO. Kinetics followed the pseudo-second-order model, indicating chemisorption. Langmuir isotherm gave maximum capacities of 9.11 mg/g (MB) and 12.06 mg/g (MO). Fika bentonite is a promising low-cost adsorbent for cationic and anionic dyes.
