A novel deep eutectic solvents (DES) was successfully applied as an emulsifier in vortex assisted liquid-liquid microextraction (VALLME) coupled with gas chromatography-mass spectrometry for the determination of organophosphorus pesticides in honey and fruit samples. Based on the result of toxicity study, DES provides new opportunities for the safe delivery and application. The predominant parameters affecting extraction efficiency were thoroughly optimized and studied in detail. Under optimum parameters, the calibration curve was determined in the concentration range of 0.1 to 200 µgL with excellent determination coefficients values of 0.9989 to 0.9999. Limit of detection and limit of quantification were found to be 0.01 - 0.09 µgL and 0.03 - 0.2 µgL, respectively. Application of the developed method to honey and fruit samples gave acceptable recovery values 83 - 109% with relative standard deviation below than 9.5%. The suggested approach has also proven to be simple, cost-effective, rapid, and non-toxic in nature.
一种新型的深共晶溶剂(DES)成功地被应用于涡旋辅助液 - 液微萃取(VALLME)中作为乳化剂,结合气相色谱 - 质谱法用于测定蜂蜜和水果样品中的有机磷农药。基于毒性研究的结果,DES 为安全输送和应用提供了新的机会。主要影响萃取效率的参数进行了彻底的优化和详细研究。在最佳参数下,在 0.1 至 200 µgL 的浓度范围内确定了校准曲线,具有优异的确定系数值为 0.9989 至 0.9999。检测限和定量限分别为 0.01-0.09 µgL 和 0.03-0.2 µgL。将所开发的方法应用于蜂蜜和水果样品,回收率为 83-109%,相对标准偏差低于 9.5%。该方法还具有简单、经济高效、快速和无毒的特点。
