In this study, the utilization of chemically modified activated carbon (AC) was investigated for malachite green (MG) dye extraction at various dye solution concentrations (50 mg/L, 100 mg/L, 150 mg/L, and 200 mg/L). The experimental variables were temperature (298 K, 308 K, and 318 K), adsorbent dose (10 g/L to 20 g/L), contact time, and pH of the starting solution (ranging from 2 to 7). The outcomes demonstrated that adsorption worked best at lower temperatures and higher pH values. Other models, though, might have been applied. The optimal adsorbent dose was found to be 20 g/L, and the maximum adsorption efficacy was recorded at pH 7.0.
