Abstract Molecularly imprinted solid phase extraction is an excellent tool for the preconcentration of trace analytes. We report on the preparation of such a material by firstly graft-polymerizing methacrylic acid onto the surface of silica gel particles, and then imprinting it by using phenol as a template and ethylene glycol diglycidyl ether as a crosslinker. The binding and recognition of phenol were examined by static methods. The binding capacity at saturation is 160 mg.g(-1) in 9 h at pH 6. The selectivity coefficients relative to o-cresol and chlorophenol are 22 and 23, respectively. The pH value has a large effect. Adsorbed phenol can be eluted easily from the imprint with diluted sodium hydroxide solution, and the material is reusable.
