“…The method has attracted much attention due to its advantages such as short extraction time, low consumption of organic solvent, and simplicity. [55][56][57] In this study, polypyrrole as a conductive polymer was coated on the surface of Fe 3 O 4 nanoparticles. The samples were first extracted by magnetic solid phase extraction (MSPE), then the eluents were recovered, and subjected to dispersive liquidliquid microextracton (DLLME) for further purification and enrichment of permethrin and deltamethrin compounds.…”

In this study, new and efficient method, magnetic solid phase extraction coupled with dispersive liquid-liquid microextracton (MSPE-DLLME) combined with gas chromatography-flame ionization detector (GC-FID) was developed for the preconcentration and determination of permethrin and deltamethrin in water samples. KEYWORDSMagnetic solid-phase extraction, dispersive liquid-liquid microextraction, permethrin, deltamethrin, gas chromatography, water samples IntroductionInsecticides on the basis of pyrethrine were first introduced in the 1950s. Pyrethrines are a class of natural substances which originates from the blossom of the chrysanthemum. Pyrethrines were, and still are, used as natural insecticides against vermin in households. Nevertheless, the production of pyrethrine is expensive and the resources are limited. For these reasons synthetic pyrethroids were developed based on the basic structure of natural pyrethrines.

“…According to the other papers, [12][13][14][15][16][17][18][19][20][21][22][23] time has no influence on extraction efficiency, because of that after formation of cloudy solution, the surface area between extraction solvent and aqueous phase (sample) is infinitely large. Thereby, transition of analytes from aqueous phase (sample) to extraction solvent is fast.…”

“…Up to now, DLLME has been successfully applied for extraction of organic and inorganic analytes. [12][13][14][15][16][17][18][19][20][21][22][23] In the present study, the applicability of the DLLME method combined with HPLC-UV for the determination of abamectin in fruit juice samples was investigated. The effects of various experimental parameters such as types and volumes of extraction and disperser solvents and salt addition on the extraction efficiency were studied.…”

Dispersive liquid-liquid microextraction (DLLME) coupled with high-performance liquid chromatography (HPLC) -UV detection was applied for the extraction and determination of abamectin (avermectin (B 1b ) and avermectin (B 1a )) in fruit juice samples. An appropriate mixture of ethanol (as the disperser solvent) and carbon tetrachloride (as the extraction solvent) was injected rapidly into a sample containing abamectin. After extraction, phase separation was performed by centrifuging the mixture and the sedimented phase was analyzed by HPLC-UV. Some effective parameters on the extraction, such as types and volumes of extractant and disperser solvents and salt effect were investigated and optimized. Under the optimum conditions, (extractant solvent: carbon tetrachloride, 30.0 µL; disperser solvent: ethanol, 1.0 mL and without salt addition), the calibration graphs were linear in the range of 2.5 -500 µg L -1 and 1.0 -500 µg L -1 with the detection limits of 0.8 µg L -1 and 0.3 µg L -1 for B 1b and B 1a in fruit juice samples, respectively. The relative standard deviation (R.S.D., n = 5) for the extraction and determination of 50.0 µg L -1 of B 1b and B 1a in the fruit juice samples were 9.2 and 7.8%, respectively. The results show that DLLME is a very simple, rapid, sensitive and efficient analytical method for the determination of abamectin in fruit juice samples and satisfactory results were obtained.

“…Liquid chromatographic methods using both UV-Vis [9] and mass spectrometry detectors [10] are the most common techniques of choice by forensic laboratories and they offer the highest selectivity and sensitivity in its detection. Biological samples need to be cleaned-up prior to analysis, which can be time consuming.…”

The electrochemical reduction of carbamazepine in acetonitrile (ACN) and dimethylformamide (DMF) using a glassy carbon electrode and microelectrodes has been studied. The reduction process is consistent with an Electrochemical-Chemical mechanism (EC) involving a two electron transfer followed by a first order reaction, as shown by the cyclic voltammetry and differential pulse voltammetry. Halfwave potential, number of electron transfer, diffusion coefficient and rate constant of the associated chemical reaction are reported. Detection limits are in DPV: LoD=0.92 and 0.76 μg mL -1 in ACN and DMF, respectively. Precision (%RSD) and recovery (%) values when pharmaceutical compounds (200mg carbamazepine tablets) and spiked plasma samples were tested ranged from 1.09 to 9.04% and % recoveries ranged from 96 to 104.1%.
