Batch desorption experiments were carried out on four raphia palm (Raphia hookeri) fruit biomasses sorbed with Pb, Cd, and Fe(III) ions, using HCl and NaOH as desorbing solutions. Results showed that for both acid and alkaline desorption, Pb2+ proved to be the most desorbed among the three metal ions considered. Maximum percent desorption was 98.35% on the UEN biomass.  On a general consideration, MEP biomass appeared to be the best by which the metal ions could be desorbed. The modified biomasses were more generally desorbed than the unmodified. There was a general pattern of dependence for all the metal ions considered, such that desorption decreased with increase in concentration loaded on the biomasses.
