Abstract
Modified chicken feather has been used as biosorbent for removing
chromium ions from aqueous solution. The adsorption capacity tests
were performed on an equilibrium batch basis. The parameters such as
contact time, biosorbent dose, pH etc were optimized and were found
to be 2 hrs, 100 mg & pH 6.0. Equilibrium isotherms were analyzed
for the adsorption process and Freundlich adsorption isotherm model was
found to fit the data well. The kinetics of adsorption followed
pseudo-second order model.
