The lead (II) adsorption kinetics was studied in the temperature range of 16–35 °C. Equilibrium time for 16, 25 and 35 °C was found to be less than 90 min (Fig. 1) indicating that the equilibrium time is independent of temperature. It was observed that lead removal by allspice residue is a typical sorption of metals, involving metabolically biomass, where metal removal from solution is purely due to the chemical or physical sorption, which reaches equilibrium relatively fast during the initial 0–30 min followed by diffusion into the adsorbent material which is particularly slower [28].
