2+ . The equilibrium sorption data fitted well the Freundlich model. The experimental data, when applied to the first and second-order kinetic models, followed both kinetic models with r≤ = 0.898 for GAC from animal horns and r 2 = 0.973 for commercial GAC. The results obtained showed how animal horns, a solid waste from the abattoir at the Oshodi market in Lagos metropolis, was used as an effective adsorbent for the removal of Pb 2+ ions; offering a cheap option for primary treatment of the brewery wastewater effluent.
