利用拉曼光谱法检测饮料中的甲基苯丙胺.pdfVIP

8 465 * , , , , ( , 20062) : 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 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- 1 1016 cm- 1 , 1201 cm- 1 处出现了强烈的拉曼 信号, 这些特征稳定存在, 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 : 拉曼光谱; 甲基苯丙胺; 加标试验; 表面增强技术; 超高效液相色谱串联飞行时间质谱连 用 : O 657 . 37; O 437 . 3 : A : 2011) Detect ing A mphet amine in D inks U sing Raman Spect oscopy * ZH A N G Jinping, L U Xinan , YA N G Jie, YA NG Guimei, Z H U Wenjie ( Colleg e of L if e S cience , East China N or mal Univ er sity , Sh anghai 200062 , China) Abstract: T his a t icle int oduced a met ho d t hat can apidly detect w het he d inks in t he ma ket co nt ain met ham phetam ine.
