: A low cost adsorbent prepared from Cicerarientinum crop seeds for the removal of Congo red dye from aqueous solution has been studied. Experiments in batch technique were carried out to study the removal efficiency of seed husk of Cicerarientinum crop towards the adsorption of Congo red dye by stirring it with Cicerarientinumcrop seed husk powder. Kinetic study of adsorption and equilibrium studies were carried out by varying different parameters like contact time, initial concentration of Congored solution, adsorbent dose, initial pH of Congo red solution and temperature. An adsorption rate model has been developed. The experimental data have also been studied in light of Langmuir and Freundlich adsorption isotherm. Adsorption equilibrium data fit most satisfactorily to Langmuir adsorption isotherm model.
