Adsorption Isotherm Study for Activated Carbon Produced from Cassava Peel

Abstract

Adsorption isotherm study of Activated Carbon produced from cassava peel was carried out using phenol solution as the adsorbate. Langmuir and Freundlich isotherm models were employed for the study. Varying ratios of 1:1, 0.75:1, 0.5:1, and 0.25:1 activating agent to cassava peel were used for the formulation of the Activated Carbon. The Freundlich R² value for the 1:1, 0.75:1, 0.5:1, and 0.25:1 formulations was 0.822, 0.979, 0.971 and 0.974, respectively. While the Langmuir R² value for the 1:1, 0.75:1, 0.5:1, and 0.25:1 formulations was 0.021, 0.139, 0.001 and 0.894, respectively.
