建立苹果表面残留的敌百虫农药的拉曼光谱无损检测技术。方法 利用激光显微拉曼光谱技术, 以苹果为载体, 敌百虫农药为研究对象, 探讨苹果表面敌百虫农药的快速无损检测方法。结果 敌百虫农药的拉曼特征频率较为丰富, 选取441 cm?1 (P-O键振动)和620 cm?1(C-Cl键振动)处的拉曼信号可识别苹果表面敌百虫农药残留, 检测限为4800 mg/kg。结论 本研究对实现水果表面敌百虫农药残留的快速、无损伤检测具有重要意义。 |

Objective To establish a method for the determination of trichlorfon pesticide on apple’ surface by Raman spectroscopy. Methods The paper investigated the use of Raman spectroscopy to detect commercially available organophosphorus pesticide namely trichlorfon on apples’ surface. Results Trichlorfon had rich Raman characteristic frequencies. Among the characteristic frequency, 441 cm?1and 620 cm?1 could be used to identify the trichlorfon residue on apples’ surface with the lowest detection limit of 4800 mg/kg. Conclusion It has an important significance for the non-destructive and rapid detection of trichlorfon pesticide in fruits. |
