“…Most of the analytical methods which are used for the analysis of PEs, such as GC or LC with various detection systems and sample preparation methods, have been documented . Different extraction methods such as LLE , SPE , LPME , DLLME , SPME , hollow‐fiber liquid–liquid–liquid microextraction (HF‐LLLME) , stir bar sorptive extraction (SBSE) , DSPE and MSPE were used as pretreatmenttechniques in PEs analysis. However, each of these methods has advantages and disadvantages that mentioned above.…”

A novel liquid-liquid microextraction method, namely, solvent-vapor-assisted liquid-liquid microextraction for the determination of dimethyl phthalate, diethyl phthalate, dibutyl phthalate and bis(2-ethylhexyl) phthalate in the aqueous samples using gas chromatography with mass spectrometry was developed. In the proposed method, extracting solvent was heated, and solvent vapor as the extracting phase was injected into the sample solution. As a result of the low temperature of the sample solution and higher density of the extracting phase than the aqueous medium, solvent vapor was condensed and an organic-phase drop formed in the bottom of sample tube. Because of the gas status of the extracting solvent, the surface area between the extracting solvent and the aqueous sample was remarkably high. Under the optimized conditions, tetrachloride carbon was used as an extracting solvent. The method shows high coefficient of determination (R ) values in the range of 0.5-200 and 1.0-200 ng/mL for the target analytes. Enrichment factors and limits of detection for the studied phthalates are obtained in the ranges of 2800-3000 and 0.15-0.3 ng/mL, respectively. Recoveries and relative standard deviations were in the range of 80.0-100.0 and 2.2-7.8%, respectively. The proposed method successfully used for analysis of several aqueous samples.

“…In 2012, Liu et al 138 used water-miscible ionic liquid (IL) for the first time as a new multifunctional acceptor phase in the three-phase HF-LPME method. This method was applied for the isolation and preconcentration of polycyclic In 2013, Chao et al 143 combined ultrasound-assisted push/pull perfusion and hollow-fiber liquid-liquidliquid microextraction for online extraction of phthalate esters in liquid samples and called ultrasound-assisted push/pull perfusion UPP-HF-LLLME. They used ultrasonic irradiation to speed up the analyte transfer and a push/pull syringe pump as the driving source to spray the acceptor phase and reduce the perfusion pressure, permitting on-line coupling of HF-LLLME to HPLC.…”

Liquid-phase microextraction (LPME) methods including single-drop microextraction (SDME), hollow-fiber LPME (HF-LPME), and dispersive liquid-liquid microextraction (DLLME) have in the very short time since their invention grabbed the attention of scientists. Up to now, LPME methods have shown important innovations for the extraction and preconcentration of both inorganic and organic trace analytes from different matrices. These LPME methods offer unique advantages such as high preconcentration factor for target analytes in a single step, low cost, simplicity, excellent preconcentration capability, sample cleanup and integration of steps, and combined use with almost every analytical measurement technique. We describe the milestones and the combined use of different types of LPME methods as well as the green aspects and advantages and shortcomings of known LPME protocols. In addition, we discuss the main results and innovations of different types of LPME published in the period 2010-2016 and we compare the performance of these techniques to that of other recent techniques.
