以顺式氯氰菊酯为测试化合物，对太赫兹(THz)光谱作为潜在农药残留分析工具的可行性进行了评价。用傅里叶变换光谱仪测量了在20-400 cm-1频率范围内的太赫兹光谱。冷冻干燥能有效地去除样品中水分的干扰。顺式氯氰菊酯在有无生物基质(如菠菜)和其他农药化合物(如氟二氰胺)存在时的吸收波数相似。商品制剂Adion中的粘土和乳化剂对顺式氯氰菊酯的吸收有干扰作用。进一步确定太赫兹方法的灵敏度和检测下限的工作正在进行中。[关键词]太赫兹、农药、光谱学、顺式氯菊酯、冻干、蔬菜
The feasibility of terahertz (THz) spectroscopy as a potential pesticide residue analytical tool was evaluated by using cis-permethrin as the test compound. THz spectra were measured by fourier-transform spectroscope at the THz region, frequency range from 20 to 400 cm-1. Freeze-drying was effective to remove interference of water from samples. The absorption wave numbers of cis-permethrin were similar with or without the presence of biological matrix such as spinach, and other pesticide compound such as fludioxonil. The clay and emulsifier in the commercial formulation Adion, interfered with the absorption of cis-permethrin. Further works to determine the sensitivity and detection limit of the THz methodology are in progress.[Keywords] terahertz, pesticide, spectroscopy, cis-permethrin, freeze-dry, vegetable
