Ionic liquids modified dummy molecularly imprinted microspheres as solid phase extraction materials for the determination of clenbuterol and clorprenaline in urine

•Ionic liquid modified dummy imprinted microspheres (DMIMs) were synthesized.•DMIMs-SPE for rapid isolation of clenbuterol and clorprenaline in urine.•Matrix interferences were removed and analytes were concentrated.•Problem of template leakage on quantitative analysis was eliminated. New ionic liqu...
