Abstract：The kaolinite 2 Mercaptobeniazole complex was prepared and its adsorbability of some heavy mental ions in solution was investigated.It was proved that its adsorbability(of Pb 2+ ?Hg 2+ ?Zn 2+ )was much better than that of the pure kaolinite or that of the kaolinite which was only modified on surface.The maxim adsorption of Pb 2+ ,Hg 2+ ,Zn 2+ by Kaolinite 2 Mercaptobeniazole was 16.91μmol·g -1 ,20.52μmol·g -1 ,10 80μmol·g -1 respectively.

Key words：kaolinite 2 mercaptobeniazole; heavy mental ions; absorbability
