Abstract
A new type of non-stoichiometric adsorbent for removal of lead is prep ared by inorganic sythesization. This adsorbent can effectively remove trance lead in neutral water under normal temperature with excellent selectivity. The aquatic chemistry of Pb( II), optimal conditions for the preparation of adsorbent, the adsoption isotherm of lead at pH = 7 , and the effect of pH values on adsorption were investigated. The ads option kinetics of lead can be described by the pore diffusion control mechanism.
