Abstract: A new type of Pb2+ chromogenic imprinted adsorbent was prepared by sol-gel approach with Pb2+ as the template and dithizone grafting onto the silica gel surface. The adsorbent was characterized by FT-IR and scanning electron microscopy. The adsorption property, chromogenic property and selective recognition ability of the adsorbent were studied by equilibrium-adsorption method. Results showed that the dithizone was coated on the silica gel through hydrogen bond. The chromogenic limit of the printed adsorbent was 10 μmol/L, the relative selectivity coefficient was 250 while Cd2+ existed; the extraction behavior of the Pb2+ was conformed by Langmuir's equation and the enthalpy of adsorption was 66.054 kJ/mol. The adsorption capacity reached 97% in 5 min and it could be used for separation and determination of trace Pb2+ in the waste water
