The capacity of adsorption of allspice residue was corroborated by the presence of lead ions onto its surface. Fig. 8a and b shows the SEM image and the elemental analysis of adsorbent before and after contact with lead solutions, respectively. It can be seen that raw allspice residue contains aluminium, calcium and potassium and only lead ions are present in allspice residue after the sorption process. This indicates that aluminium, calcium and potassium are transferred to the aqueous solution. As shown in Table 8 the percentage of Al, Ca and K is quite low compared with C and O.
