A new method coupling matrix solid phase dispersion(MSPD) with capillary electrophoresis was developed for the determination of acrylamide in rice product.The optimized conditions obtained in experiments were as follows:Florisil and C18 were used as a mixed dispersant with a mass ratio of 1∶4.The mass ratio of sample to dispersant was 5∶9.The mixture of 10 mL acetone-dichloromethane(6∶4) was used as elution solvent.Under the optimized experimental conditions,20 mmol/L borate solution(pH 8.4) was used as buffer.The sample was separated at a constant voltage of 15 kV.The linear range of acrylamide was in the range of 10-200 μg/mL,with a correlation coefficient(r) of 0.999 8.The limit of detection(LOD,S/N=3) was 0.62 μg/mL for acrylamide and the recoveries were in the range of 85.7%-96.4%.
