“…Various sample preparation methods ranging from conventional to advanced extraction methods including liquid-liquid extraction (LLE) [9], solid-phase extraction (SPE) [10], solid phase microextraction [11], quick, easy, cheap, effective, rugged, and safe [12], and dispersive liquid-liquid microextraction (DLLME) [13] have been used for the extraction and preconcentration of OCPs from various samples. Among these methods, SPE has been one of the most widely sorbent-based methods used for the isolation and concentration of target analytes from various matrices [14,15]. Its advantages over previously used methods, such as LLE, are its simplicity, high analyte preconcentration factors, the reusability of SPE sorbents, and the use of relatively small volumes of organic solvents [16].…”

An efficient analytical method has been developed based on dispersive solid‐phase extraction followed by gas chromatography‐mass spectrometry for the determinations of 13 organochlorine pesticides in fruit juice samples. In this method, dispersive solid phase extraction was used for the extraction of target analye using iron‐doped zinc oxide nanoparticles supported with silica as a sorbent. Different experimental parameters affecting the extraction efficiencies the proposed method were carefully optimized. Under the optimum conditions, the calibration graphs were linear in the concentration range of 0.6–100 ng/mL with coefficients of determinations in the range of 0.9927–0.9991. The limits of detection and quantification determined as 3 and 10 times the signal‐to‐noise ratio were in the range of 0.01–0.03 and 0.6–1.0 ng/mL, respectively. Intra‐ and inter‐day precision studies of the proposed method, expressed as relative standard deviations, were in the range of 2.1%–9.2% and 2.2%–9.7%, respectively. The recoveries of the spiked fruit juices samples were in the range of 81.4%–105.1% with the corresponding relative standard deviations ranging from 1.0%–8.8%. In general, the proposed method demonstrated satisfactory analytical performance. Thus,it could be used as simple and attracive alternative method for the extraction of organochlorine pesticides from fruit juice sample and other related matrices.
