1-30 n-alkane groups, phenyl, and so on; P denotes polar groups, which comprise C1-12 n-alkane groups jointing with Cl, Br, CN, amino group, benzenesulfonic group, sulfonic group, carboxyl group, quaternary ammonium group, alcohol group, and so on. The preparation method of the above mentioned separation material comprises the following steps: acidification preprocessing of silica gel, hydrating, copolymerizing a mixture of non-polar silane reagent and polar silane reagent on the hydrated silica gel surface, filtering, washing, drying, and so on. The separation material of the present invention has both non-polar groups and polar groups, which can provide hydrophobic applied force and several kinds of polar applied forces, and thereby improve greatly the selectivity of separation and enrichment. The separation material obtained through the preparation method of the present invention has merits such as uniform and stable bonding groups on the surface, larger bonding amount and so on, and can be applied to liquid chromatogram chromatography and solid phase extraction."/>
