Abstract

Highlights: DES-VALLME was developed for determination of OPPs in honey and fruit samples by GC–MS analysis. High analytes recoveries were achieved with the proposed method. A novel DES enhanced the VALLME performance. DES-VALLME will enable trace OPPs determination in honey and fruits samples. Abstract: 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 −1 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 −1 and 0.03 – 0.2 µgL −1, 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.
