Abstract

In this study, a biosorbent was successfully applied to remove thorium metal Th(IV) from aqueous solutions. Moringa oleifera bark was fractionated into 60-mesh particles to perform characterization and extraction experiments. The adsorption kinetics for Th(IV) followed a pseudo second-order model, and small difference between the experimental and calculated Q_eq values [4.38 and 3.32 mg/g for Q_eq(exp.) and Q_eq(cal.), respectively] was observed. The maximum capacity (Q_max) value calculated using the modified Langmuir equation 5.46 mg/g.
