Application of filter-based emulsif
Application of filter-based emulsification microextraction to real samples
The proposed method was applied for the determination of the chlorophenols under investigation in
some samples including the tap, waste, and river waters. Initially, these samples were prepared
according to Section 2.2, and they were then investigated by filter-based emulsification
microextraction. The results obtained showed that the concentrations of all the target contaminants
in the waste and tap waters were below the LOD for the method. On the other hand, these results
revealed the existence of chlorophenols in the river water sample. To investigate the matrix effects,
all the real samples were spiked with proper amounts of the analytes, and the relative recoveries
were subsequently calculated. The results obtained showed that the different matrixes used for all
the water samples had no significant effect on the extraction efficiency, and obtaining high relative recoveries (96–107%) proved this fact (Table 3). The GC–FID chromatograms for the river water
samples for the non-spiked and spiked ones at the concentration level of 50 ng mL-1 for the analytes
are shown in Fig. 2.
4 Conclusion
A simple approach was applied for the derivatization and extraction of some chlorophenols including
2-chlorophenol, 3-chlorophenol 4-chlorophenol, and 2,4,6-trichlorophenol from aqueous sample
solutions. The method termed as filter-based emulsification microextraction provided a proper
characteristics so that it simultaneously resolved some problems of the dispersive microextraction
methods. It eliminated the centrifugation step, which has been mentioned as the bottleneck in the
automation of the method, and enhanced sample clean-up of the method by filtration of the
extracting phase. The most remarkable outcome was the derivatization and extraction processes
being performed in just about 90 s. The parameters affecting the method were optimized, and the
method was used for the preparation of some real samples including the river, tap, and wastewater
samples. The results obtained showed that the different matrixes used for all the water samples had
no significant effect on the extraction efficiency, and obtaining high relative recoveries (96–107%)
