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.
