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 Qeq values [4.38 and 3.32 mg/g for Qeq(exp.) and Qeq(cal.), respectively] was observed. The maximum capacity (Qmax) value calculated using the modified Langmuir equation 5.46 mg/g.
