Abstract: The invention discloses a mesoporous silicon composite lead ion imprinted polymer and its preparation method and use, and belongs to the technical field of material preparation and separation. The mesoporous silicon composite lead ion imprinted polymer is prepared from hexadecyl trimethyl ammonium bromide as a template, lead ions as template ions, aminopropyltriethoxysilane or N-aminoethyl-gamma-aminopropyltrimethoxysilane as a functional monomer, tetraethyl orthosilicate as a cross-linking agent and 2mol/L of a sodium hydroxide aqueous solution as an initiator. A selective dynamic adsorption experiment on selective recognition performances of the ion imprinted polymer proves that the mesoporous silicon composite lead ion imprinted polymer obtained by the preparation method has excellent lead ion identification performances.
