Activated carbon from coconut frond as adsorbent for removal of kongo red
The aim of this study is to investigate the potential use of activated carbon from coconut frond (CFAC) as an adsorbent for the removal of congo red (CR) dye from aqueous solution. The effect of various operational parameters such as adsorbent dosage (0.1, 0.3, 0.5, 0.7, 1.0, 3.0 and 4.0 g), initial...

| Summary: | The aim of this study is to investigate the potential use of activated carbon from coconut frond (CFAC) as an adsorbent for the removal of congo red (CR) dye from aqueous solution. The effect of various operational parameters such as adsorbent dosage (0.1, 0.3, 0.5, 0.7, 1.0, 3.0 and 4.0 g), initial dye concentration (50, 100, 200, 300 and 400 mg/L), contact time (4, 8, 12, 16, 20, 24 and 28 hours) and pH (pH 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12) were studied. The study showed that up to 99.29% of CR removal can be achieved under optimum condition (adsorbent dosage: 3.0 g, initial dye concentration: 100 mg/L, contact time: 24 hours and pH: 1). the experimental data was analyzed with the Langmuir and Freundlich adsorption isotherm model. The best-fitted
data was obtained with the Langmuir model. This study indicates that activated carbon based on coconut frond has the potential to become low-cost adsorbent for the removal of congo red in water effluent. |
