Abstract

Adsorption of Pb2+ ion by a tartrate intercalated MgAl layered double hydroxides MgAlTA LDHs was studied The adsorption isotherms and kinetics were investigated as a function of various experimental parameters using batch adsorption experiments The results indicated that the adsorption isotherm was well described by Sips model The kinetic adsorption data were fitted well to the pseudosecondorder kinetic equation The adsorption of Pb2+ was controlled mainly by the chemical process combined with intraparticle diffusion Parameters of adsorption thermodynamic suggested that the interaction of Pb2+ adsorbed by MgAlTA LDHs adsorbents was thermodynamically spontaneous and endothermic
