摘要:

利用三维荧光光谱技术结合二阶校正算法对尿液中冰毒、 3,4-亚甲基二氧基甲基苯丙胺、 可卡因和吗啡4种毒品进行快速定量分析. 结果表明, 平行因子(PARAFAC)、 交替三线性分解(ATLD)和自加权交替三线性分解(SWATLD)算法均能很好地分辨出待测组分, 且通过PARAFAC与SWATLD算法解析三维光谱数据获得的尿液背景干扰下4种毒品的平均回收率为92.8%~106.1%, 相对误差低于8%. 三维荧光光谱结合二阶校正算法可用于常见毒品滥用者的快速检测, 为缉毒禁毒工作提供新的检测手段.

Abstract:

A novel method was developed for the determination of methamphetamine, 3,4-methylenedioxymethamphetamine(MDMA), cocaine and morphine in urine by excitation-emission matrix fluorescence coupled with second-order calibration algorithm. The results showed that the excitation and emission spectra of the four illegal drugs can be resolved accurately based on parallel factor analysis(PARAFAC), self-weighted alternating trilinear decomposition(SWATLD) and alternating trilinear decomposition(ATLD). Additionally, the average spike recoveries are 92.8%—106.1%, and the relative errors are below 8% for all the illegal drugs in the presence of interference of urine by PARAFAC and SWATLD algorithms. The satisfactory results obtained in this work indicate that the excitation-emission matrix fluorescence coupled with second-order calibration is an effective and fast method for screening illegal drug abuses, and it provides a new detection technique for narcotics department.
