摘　　要：利用拉曼光谱技术建立了快速检测饮料中甲基苯丙胺的方法。对市场出售的可乐、脉动、橙汁三种饮料进行甲基苯丙胺不同加标浓度的表面增强拉曼光谱检测,结果表明加标饮料的拉曼光谱对比未加标饮料出现了明显的变化,在991 cm-11、016 cm-1,1201 cm-1处出现了强烈的拉曼信号,这些特征稳定存在,可以作为鉴定此3种饮料中是否含有甲基苯丙胺的依据。拉曼光谱的检测结果,与利用超高效液相色谱-串联飞行时间质谱方法检测甲基苯丙胺得到的定性试验结果相一致。该方法准确、快速、操作方便,有很广阔的应用前景。This article introduced a method that can rapidly detect whether drinks in the market contain methamphetamine.Three kinds of popular drinks,Coca Cola,Mizone and orange juice were selected as samples.The Raman spectra of the sample drinks before and after adding methamphetamine were compared,and there were characteristic peaks at 991 cm-1,1016 cm-1,1201 cm-1appeared in the Raman specta of the sample drinks added methamphetamine The results of Raman test were consistent with the methamphetamine detection by using UPLC-Q TOF MS.Thus Raman spectroscopy with surface-enhanced technology is an accurate,quick and user-friendly treating method and it has a broad application prospect.
