Abstract: A novel surface imprinting material based on modification of silica gel had been successfully synthesized. Propazine was chosen as template, and hydrogen bond was used as interaction between template and monomer. FT-IR and elemental analysis support the structure of molecularly imprinted polymer (MIP) layer. The thickness of imprinted layer calculated front pore size was 0.3 nm. It had been demonstrated that the vinyl functional monomer layer of the silica surface could not only copolymerize with monomer and crosslinker effectively, but also force the template into the polymer shells, and thus formed selective binding site. Competitive rebinding test was carried out in aqueous media, and MIP was found as a more effective sorbent than non-imprinted polymer (NIP) toward four triazines pesticides
