Abstract

The invention provides an alkene-silica gel bonded new material. A processing method of the alkene-silica gel bonded new material comprises following steps: an alkene-silica gel bonded material is obtained via bonding the surface of a silica gel material with alkene-containing silane, and then is subjected to chain combination and crosslinking with a chain combination monomer so as to form ball-membrane structures of the chain combination monomer on the surface of the alkene-silica gel bonded material, and obtain the chain combination coated silica gel absorption new material. Beneficial effects of the alkene-silica gel bonded new material are that: the alkene-silica gel bonded new material possesses excellent absorption effects on polar compounds and nonpolar compounds, can be used with more elution solvents, possesses a wider application range, and is high in selectivity, versatility, and sample loading amount. Filling material synthesis steps of the alkene-silica gel bonded new material are simple; operation is simple; and repeatability is excellent.
