The adsorption potentials of Senna occidentalis Seeds (SoS) Activated Carbon (AC) on the removal of Congo red dye from aqueous solutions has been studied by employing equilibrium adsorption technique, adsorption isotherm and kinetics models. The equilibrium adsorption parameters varied were initial dye concentration, carbon dosage, contact time, pH and temperature. Langmuir, Freundlich and Temkin were chosen as the isotherm models while pseudo first-order, pseudo second-order and intra-particle diffusion were chosen as the kinetics models. The correlation coefficient (R2) found at 0.9962 and dimensionless separation factor (RL) at 0.0099 has confirmed that the best fitted model that described the adsorption process of CR dye is the Langmuir adsorption isotherm. Similarly, kinetics of the adsorption processes have been studied and found to be pseudo second-order kinetics. Based on this research findings, Senna occidentalis Seeds Activated Carbon can be said to have potentials for dye removal from effluents of industries, such as; textile, leather, paper, rubber, cosmetics etc.
