Abstract: A rapid, simple and highly selective accelerated solvent extraction (ASE) and matrix solid phase dispersion (MSPD) using molecularly imprinted polymer method has been developed for the determination of monocrotophos in soil. The soil sample is dispersed with molecularly imprinted polymer and loaded into the extraction cell. After two accelerated solvent extraction steps, some impurities including some OPPs were washed when CH2Cl2 was used as the solvent in the first extraction step while monocrotophos was eluted separately by 10 % CH3OH-CH2Cl2 in the second extraction step. The molecularly imprinted polymer as dispersing agent showed good performance for selectively discriminating monocrotophos from other impurities. Monocrotophos could be selectively extracted from soil and quantitive recovery of monocrotophos was 99.3 % at fortification level of 1 μg/g
