“…Comparison of PEG and graphene-PEG fibers, based on the sol-gel technique, also showed a 2 fold improvement in extraction efficiency when graphene was added to the fiber [118,126] for determination of VOCs and organophosphate ester flame retardants in water samples. However, it would appear that a similar issue as that observed for CNTs regarding aggregation and a decrease in surface area also occurs in graphene sol-gel base fibers.…”

“…One of the main advantages of sol-gel technology is its capability to incorporate the desired material into the final product. Several materials were incorporated into the polymer network by sol-gel technique to tune the properties of the coating materials including crown ether (Figure 5a) [114], carbon nanotubes (Figure 5b) [115,116], graphene [117,118], ILs (Figure 5c) [119,120], and MNPs (Figure 5d) [15].…”

The development of new support and geometries of solid phase microextraction (SPME), including metal fiber assemblies, coated-tip, and thin film microextraction (TFME) (i.e. self-supported, fabric and blade supported), as well as their effects on diffusion and extraction rate of analytes were discussed in the current review. Application of main techniques widely used for preparation of a variety of coating materials of SPME, including sol-gel technique, electrochemical and electrospinning methods as well as the available commercial coatings, were presented. Advantages and limitations of each technique from several aspects, such as range of application, biocompatibility, availability in different geometrical configurations, method of preparation, incorporation of various materials to tune the coating properties, and thermal and physical stability, were also investigated. Future perspectives of each technique to improve the efficiency and stability of the coatings were also summarized. Some interesting materials including ionic liquids (ILs), metal organic frameworks (MOFs) and particle loaded coatings were briefly presented.

“…The commercialized SPME fiber can be only extracted by approximately 50 times and is very fragile. A homemade SPME fiber has longer service life and better stability but requires a cumbersome preparation process 28,39 . DLLME requires small amounts of aqueous samples and organic solvents and has relatively high recoveries and low LOD and LOQ.…”

This study developed a novel method for the determination of 13 organophosphate esters (OPEs) in aqueous samples through the optimization of solvent demulsification-dispersive liquid-liquid microextraction based on solidification of floating organic drop procedure coupled with ultra-high-performance liquid chromatography-tandem mass spectrometry. The proposed method was rapid and accurate and could be used in field applications. Under the most suitable conditions, the limit of detection and limit of quantification ranged from 0.16 ng/L to 20.0 ng/L and from 0.55 ng/L to 66.7 ng/L, respectively. The enrichment factors (EFs) ranged from 30 to 46. The relative standard deviations were less than 15%. The spiked recoveries ranged between 68.2% and 97.7% in the analysis of actual aqueous samples. The proposed method was convenient, environment friendly, and time and solvent saving and could be used in field applications compared with other methods. Various concentrations and types of OPEs were detected in tap water, river water, and effluent of sewage treatment plant. Effluent samples had the highest detected levels and types of OPEs.

“…GC methods are used to determine compounds with no polarity, using non-polar inert phases, commonly (5% phenyl)-methylpolysiloxane such as HP5 and DB-5MS. The column length ranges from 15 to 30 m; commonly used columns are 30 m length × 0.25 mm internal diameter × 0.25 µm film thickness [31,87]. There are complications when separating and detecting some OPFRs' constituents depending on the physical properties of the inert phase.…”

Spatiotemporal Distribution and Analysis of Organophosphate Flame Retardants in the Environmental Systems: A Review

In recent times, there has been a cumulative apprehension regarding organophosphate flame retardants (OPFRs) owing to their high manufacturing and usage after brominated flame retardants were strictly regulated and banned from being distributed and used in many countries. OPFRs are known as the main organic pollutants in the terrestrial and aquatic environment. They are very dangerous to humans, plants and animals. They are also carcinogenic and some have been implicated in neurodevelopmental and fertility challenges. OPFRs are distributed into the environment through a number of processes, including the usage, improper disposal and production of materials. The solid phase extraction (SPE) method is suggested for the extraction of OPFRs from water samples since it provides high quality recoveries ranging from 67% to 105% and relative standard deviations (RSDs) below 20%. In the same vein, microwave-assisted extraction (MAE) is highly advocated for the extraction of OPFRs from sediment/soil. Recoveries in the range of 78% to 105% and RSDs ranging from 3% to 8% have been reported. Hence, it is a faster method of extraction for solid samples and only demands a reduced amount of solvent, unlike other methods. The extract of OPFRs from various matrices is then followed by a clean-up of the extract using a silica gel packed column followed by the quantification of compounds by gas chromatography coupled with a mass spectrometer (GC–MS) or a flame ionization detector (GC-FID). In this paper, different analytical methods for the evaluation of OPFRs in different environmental samples are reviewed. The effects and toxicities of these contaminants on humans and other organisms are also discussed.
