Sorption Modles Of Lead(II) Ions Onto Agricultural Tuber Waste Bio Mass

I.A.Okoro

The sorption capacities of tuber agricultural wastes for the removal of lead(II) ion fromaqueous solution were studied. The data obtained therefore were modeled using two physical chemistry isotherm models; Langmuir and Dubinin-Radushkevichmodels respectively. The results of these modeling showed that each of these tuber waste biomass fitted into these established models. The Qmax obtained from the modeling was thus;Qmax for yampeels>Qmax for cassava peels>Qmax for sweet potato peels. The sorption energy obtains showed a reverse trend:- sweet potato peels>cassava peels>yam peels. The obtained langmuir constants for these tuber waste biomass are closely related in values.
