Nowadays,the abuse of illegal drugs has been an increasingly grim problem in the world.Excitation-emission matrix fluorescence combined with parallel factor analysis was used to make a quantitative analysis of the simulated amphetamine-type illegal drugs.Satisfactory results were achieved for simultaneous determination of methamphetamine (MAM) and 3,4-methylenedioxymethamphetamine (MDMA) in the presence of adulterants.The average recoveries were (99.8 ± 0.6)％ and (101.6 ± 5.7)％ for MAM and MDMA,respectively.Figures of merit including root-mean-square error of calibration and prediction,sensitivity and selectivity were investigated to evaluate the performance of the proposed method.The limits of detection were 0.054 and 0.002 1 μg/mL for MAM and MDMA,respectively.
