Kinetic and Thermodynamic Study of Adsorption of Ionic Dyes

Kinetic and thermodynamic study of removal of ionic dyes on low cost adsorbents and their derivatives. Four ionic dyes belonging to different classes were selected. The locally available low cost materials like raw agricultural wastes, carbonized agricultural wastes, surfactant modified agricultural wastes, surfactant modified agricultural waste carbon, low cost clays and low cost nanoadsorbents were evaluated for the adsorption of dyes from simulated dye effluent containing dyes. The effect of experimental conditions like effect of concentration, pH,temperature and reaction time were optimized. The kinetics and thermodynamics of the adsorption were evaluated by using well known kinetic, equilibrium and isotherm models.
