A sensitive and fast ultrasound-assisted dispersive liquid-liquid microextraction procedure combined with ion mobility spectrometry has been developed for the simultaneous extraction and determination of bendiocarb and azinphos-ethyl. Experimental parameters affecting the analytical performance of the method were optimized: type and volume of extraction solvent (chloroform, 150 µL), pH (9.0), type and volume of buffer (ammonium buffer pH = 9.0, 4.5 mL) and extraction time (3.0 min). Under optimum conditions, the linearity was found to be in the range of 2–40 and 6–100 ng/mL and the limits of detection (LOD) were 1.04 and 1.31 ng/mL for bendiocarb and azinphos-ethyl, respectively. The method was successfully validated for the analysis of bendiocarb and azinphos-ethyl in different samples such as waters, soil, food and beverage samples.

超声辅助液-液微萃取-离子迁移谱法同时测定水,土壤,食品和饮料样品中的苯达威和谷硫磷

已经开发了一种灵敏且快速的超声辅助分散液-液微萃取程序,并结合了离子迁移谱法,用于同时萃取和测定苯达威和谷硫磷的含量。优化了影响该方法分析性能的实验参数:萃取溶剂的类型和体积(氯仿,150 µL),pH(9.0),缓冲液的类型和体积(铵缓冲液pH = 9.0、4.5 mL)和萃取时间(3.0)分钟)。在最佳条件下,线性度被发现在2–40 ng / mL和6–100 ng / mL的范围内,苯达威和谷硫磷的检出限(LOD)分别为1.04和1.31 ng / mL。该方法已成功验证了该方法可用于分析不同样品(例如水,土壤,食品和饮料样品)中的苯达威和谷硫磷。
