One of the heavy metals can pollute the waters is metal ion of Pb2+. Concentration of ions Pb2+ can be removed by adsorption method. The purposes of this research are to observe the effect of stirring rate and concentration on the adsorption of metal ions Pb2+ using adsorbents tricalciumphsphate (TCP) and determine a suitable adsorption kinetics model. Pb2+ solution (2,736 mg / L, 8,546 mg / L …
