摘　　要：Organic-inorganic hybrid and carbaryl-imprinted capillary monolith was synthesized via methacrylic acid（MAA） as functional monomer, γ-methacryloxypropyltrimethoxysilane（γ-MAPS） as crosslinker and carbaryl as template molecule in an acetonitrile/dichloromethane mixture（1：4, volume ratio）. With the capillary column obtained from this monolith, three carbamates（carbaryl, fenobucarb and metolcarb） were separated effectively by electrochromatography with the kMIp/kNlP values of 7.57, 1.27 and 1.64, respectively. In 20 mmol/L phosphate buffer solution（pH=3.5） with 30%（volume fraction） of acetonitrile, carbaryl was separated directly from the three-carbamate mixture（carbaryl, fenobucarb and metolcarb） with an effective 15 cm-length imprinted column.Organic-inorganic hybrid and carbaryl-imprinted capillary monolith was synthesized via methacrylic acid（MAA） as functional monomer, γ-methacryloxypropyltrimethoxysilane（γ-MAPS） as crosslinker and carbaryl as template molecule in an acetonitrile/dichloromethane mixture（1：4, volume ratio）.
