A method based on direct immersion solid-phase microextraction (DI-SPME) coupled with high performance liquid chromatography combined with post-column photochemically induced fluorimetry derivatization and fluorescence detection (HPLC-PIF-FD) was developed to extract three pyrethroid insecticides, i.e. cyfluthrin, cypermethrin, and flumethrin from water samples. A sol-gel based coating fiber using 3-(trimethoxysilyl propyl) amine as precursor was prepared and used for the extraction of the pyrethroids from groundwater samples. A post-column photochemical reactor was designed and constructed for the derivatization of these environmentally important pollutants to increase their fluorescence sensitivity and determination in HPLC. The parameters affecting extraction process (extraction time and temperature, pH, salt addition, and co-solvent) and desorption step (solvent, desorption time, and temperature) of the analytes from the sol-gel-based fiber, along with photochemical reaction conditions were investigated. The developed method proved to be relatively rapid, simple, and easy and offers high sensitivity and reproducibility. Linear dynamic ranges (LDR) for these insecticides were ranged between 0.25 to 50 microg/L. The regression coefficients were satisfactory (R(2) > 0.984) for these pyrethroids. The limits of detection and limits of quantification varied between 0.09 and 0.35 microg/L and 0.25 and 1.00 microg/L, respectively. Relative standard deviation RSDs values varied between 4.41% and 6.20%. Relative recoveries obtained from analysis of Jajroud river water sample ranged between 94% and 104%.

“…This technique has important advantages over conventional extraction techniques due to its ease of use, its being rather rapid, portable, completely solvent-free, no need of clean-up procedures and simple instrumentation [4,5]. SPME has been used by various researchers for a variety of environmental applications including the analysis of polychlorinated biphenyls (PCBs) [6,7], hydrocarbons [8][9][10], PAHs [11][12][13], substituted benzene compounds [14] trihalomethanes [15], chlorophenols [16], phenols [17] and odour compounds [18] in aqueous samples.…”

A highly porous fiber coating material was prepared and functionalized with 3-amino propyl triethoxysilane (APTES) on hexagonally ordered nanoporous silica (SBA-15). Applicability of this coating was assessed employing a laboratory made solid-phase microextraction (SPME) device and gas chromatography-mass spectrometry for the simultaneous sampling and determination of trace polycyclic aromatic hydrocarbons (PAHs) from aqueous sample solutions. A one at the time optimization strategy was applied to investigate and optimize important extraction parameters such as extraction temperature, extraction time, ionic strength and sonication time. In the optimum conditions, the relative standard deviations for deionized water, spiked with selected PAHs were between 3.3 and 7.7% (n = 3), and detection limits for the studied compounds were 4.2 and 26.1 pg mL -1 . No significant change was observed in the extraction efficiency of the new SPME fiber, over 50 extractions. The proposed method was successfully applied to the extraction and determination of PAHs in the waste water samples.

“…In recent years, studies have been focused on fabricating low cost, simple, robust and long-life fiber for the target analyte [23]. A variety of methods for the production of fibers have been developed such as sol-gel [24], and physical and electrochemical polymerization [25]. Among these, electrochemical polymerization is the method of choice as the film thickness can be controlled easily and polymers with different functional groups can be formed conveniently by changing dopant ions or using substituted monomers under controlled electrochemical conditions [26].…”
