Abstract: This study investigated the potential use of Activated Carbon from Coconut Frond (ACCF) as an adsorbent for the removal of Congo Red (CR) dye from aqueous solution. The effects of various operational parameters such as adsorbent dosage, initial dye concentration, contact time and pH were studied. The results demonstrated that up to 99.29% of CR removal could be achieved under optimum condition (adsorbent dosage: 3.0 g, initial dye concentration: 100 mg/L, contact time 24 h and pH). The experimental data were analysed using Langmuir and Freundlich adsorption isotherm models. The equilibrium data appeared to best fit the Langmuir isotherm model with a correlation coefficient of R2 = 0.9931 and maximum adsorption capacity was 9.823 mg/g. This study indicates that ACCF has the potential in becoming a low-cost adsorbent for the removal of CR in water effluent.
