“…The results obtained indicated that the EF values were between 180 and 203 and that the absolute extraction values were in the range of 54–61%. Comparison of filter‐based emulsification microextraction and some other methods used for the extraction of the chlorophenols under investigation such as DLLME‐SDME , ionic‐liquid microextraction (ILME) , SPME , solid‐phase derivative extraction (SPDE) , DLLME , and HF‐LPME is provided in Table .…”

“…Also these compounds can present significant health hazards due to their moderate bio‐accumulation and high toxicity, which increase with the increment of chlorination. The United States Environmental Protection Agency and the European Union have included chlorophenols in their list of priority pollutants . Hence, a simple, rapid, and robust analytical methodology is required to determine these compounds in different samples.…”

“…Due to the need for chlorophenols to be derived, there are many derivatization methods available for this purpose. Sulfonylation , silylation , alkylation , and acylation are some of these methods. Derivatization of the chlorophenols under investigation by ethyl chloroformate is carried out by alkoxycarbonyl (AOC) reactions .…”

In this work, an efficient microextraction method was applied for the extraction of some chlorophenols in water samples. This method, termed filter-based emulsification microextraction, is based on the dispersion of an extractant into an aqueous sample solution to accelerate the extraction process and the utilization of a Nylon syringe filter to break the emulsion. After phase separation, the method is coupled with gas chromatography as a final analyzer instrument. The overall derivatization/extraction time was about 90 s. The proposed method is centrifuge-free, and it also provides a suitable sample clean-up by filtration of the extracting phase. The effective parameters involved in the extraction method were optimized. Under the optimal experimental conditions, the method provided a good linearity in the range of 2.0-2000 ng/mL, extraction repeatabilities (relative standard deviations) below 9.4%, enrichment factors of 180-203, and limits of detection between 0.5 and 1.2 ng/mL.

“…Among the common analytical methods, GC is not the preferred method for CPs analysis owing to their medium polarity and low vapor pressure. Furthermore, sufficient clean‐up and derivatization, which is labor‐intensive and time‐consuming, is mandatory for GC analysis [10]. On the other hand, derivatization is not required when employing liquid chromatography, simplifying sample pretreatment.…”

New ternary deep eutectic solvents were prepared and applied as efficient green dispersing solvents in miniaturized matrix solid‐phase dispersion to extract chlorophenols from river sediments for the first time. High‐performance liquid chromatography coupled with a photodiode array detector was used to analyze the target analytes. The significant factors affecting the extraction were optimized as follows: dispersant (100 mg), sample (100 mg), ternary eutectic solvents (150 μl), grinding for 1 min, 450 μl of acetonitrile as the elution solvent, and vortex mixing for 20 s. Under the optimal conditions, the method exhibited excellent linearity (correlation coefficient > 0.9980), low limits of detection between 1.039–2.478 μg/g, and extraction recoveries between 93.9% and 99.2%. Furthermore, the method demonstrated excellent precision in the intra‐ and inter‐day analysis with a relative standard deviation below 6%. When compared to conventional extraction techniques, the miniaturized matrix solid‐phase dispersion considerably reduced samples and solvent usag, offering important environmental benefits. The green profile of the method was assessed using the complementary green analytical procedure index tool confirming its eco‐friendship. The technique was finally employed to evaluate sediment samples from three distinct locations along the Zuibaiji River, indicating its applicability for monitoring environmental samples.
