摘要：

<正> A new type of non-stoichiometric adsorbent for removal of lead is prepared by inorganic sythesiza-tion. 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 adsoption kinetics of lead can be described by the pore diffusion control mechanism.
