“…In general, sample preparation is usually necessary for the effective measurement of trace levels of contaminants in the sample prior to chromatography analysis. So far, various sample preparation techniques have been developed to isolate and enrich pesticide residues from different samples, such as liquid–liquid extraction , SPE , dispersive SPE , solid‐phase microextraction (SPME) , dispersive liquid–liquid microextraction (DLLME) and hollow fiber liquid‐phase microextraction . More recently, a new extraction technique called magnetic solid‐phase extraction (MSPE) has been used for the preconcentration of the pesticide residue .…”

A novel 3D-graphene (3D-G) magnetic nanomaterial was prepared and used as an adsorbent for the extraction of four neonicotinoid insecticides (acetamiprid, imidacloprid, thiacloprid, and thiamethoxam) from lemon juice sample. Then, HPLC with UV detection was applied for the determination of the neonicotinoid insecticides desorbed from the 3D-G magnetic nanomaterial. The main experimental parameters that affect the extraction efficiencies such as the amount of 3D-G magnetic nanomaterial, sample solution pH, extraction time, salting-out effect, and desorption conditions were studied and optimized. As a result, the linear concentration range of the method was from 0.3 to 100.0 ng/mL for thiacloprid, from 0.5 to 100.0 ng/mL for imidacloprid and acetamiprid, and from 1.0 to 100.0 ng/mL for thiamethoxam, with correlation coefficients of 0.9965-0.9985, respectively. The LODs of the method based on an S/N of 3 were between 0.08 and 0.2 ng/mL. The enrichment factors obtained were between 67 and 427, and the RSDs (n = 6) were in the range from 4.6 to 7.1%, and the recoveries of the method fell in the range of 88.75 to 111.60%.

“…Tobacco nicotine increases stimulation and pleasure and decreases stress and anxiety because of its effects on the neurotransmitter release (dopamine and others) in brain tissue (Benowitz, 2008;Zuo et al, 2004). On the other hand, nicotine has predominant effects on smokers and non-smokers health such as enhancement blood sugar release, blood pleasure and increase heart pulse rate because it is absorbed through the skin, mucous membranes in the mouth and nose or by the lungs during smoke inhalation (Miller et al, 2010;Shrivas and Patel, 2010). Tobacco smoking is still the commonly preferred path for intake of nicotine in spite of the fact that it often causes cancer of various organs involving lung, stomach, bladder, colon, kidney, nose and oral cavity (Banerjee et al, 2013;Yu and Chang, 2013) and also the difficulties that meet the smokers to quitting the smoking habit (Svorc et al, 2014).…”

In the present study, a highly sensitive Gas Chromatographic-Mass Spectrometric (GC-MS) method and single-step extraction procedure have been developed for the determination of nicotine level in Hookah tobacco products samples. The principle focus of the developed method is the lower limit of detection (0.025 ng mLG 1) and a wide linear range (0.03-17000 ng mLG 1) achieved that can have important implications in the determination of nicotine in any investigated samples. In addition, the accuracy and precision values of the method were in the range of 98.07-103.81 and 0.2660-1.7712%, respectively. While the extraction recovery of nicotine, when spiked to hookah tobacco products was ranged from 94.85-98.00%. The present chromatographic method showed higher sensitivity, linearity precision and accuracy, when compared with the reported chromatographic methods. Finally, the hookah tobacco products samples were used to evaluate the method applicability for the determination of nicotine.

“…Therefore, it can cause various human diseases such as peripheral vascular disease, stroke, reproductive disorder, peptic ulcer, esophageal reflux, renal disease, enhancement of malignant hypertension, lung diseases and cancer [ 21 ]. Different analytical separation procedures such as solid-phase extraction (SPE) [ 22 ], liquid-phase microextraction (LPME) [ 23 ] and SPME [ 24 ] have been reported for sampling of nicotine in biological fluids. Nicotine is a semi-volatile polar compound, so it needs to be extracted using suitable polar fiber coatings through SPME.…”

A stainless steel fiber was made porous and adhesive by platinization and then coated by nanostructured polypyrrole (PPy), using an appropriate electrophoretic deposition (EPD) method. The morphological surface structure and functional groups of the PPy-coated fiber were studied using SEM (Scanning electron microscope) instrument. The prepared fiber was used for comparison of direct immersion (DI) and electroenhanced direct immersion solid-phase microextraction (EE-DI-SPME) of nicotine in human plasma and urine samples followed by gas chromatography flame ionization detector (GC-FID) determination. The effects of the influential experimental parameters on the efficiency of the DI-SPME and EE-DI-SPME methods, including the pH and ionic strength of the sample solution, applied Direct current (DC) voltage, extraction temperature and time and stirring rate, were optimized. Under the optimal conditions, the calibration curves for the DI-SPME-GC-FID and EE-DI-SPME-GC-FID methods were linear over the ranges of 0.1–10.0 μg mL−1 and 0.001–10.0 μg mL−1, respectively. The relative standard deviations (RSDs, n = 6) were found to be 6.1% and 4.6% for the DI and EE strategies, respectively. The LODs (limit of detection) of the DI-SPME-GC-FID and EE-DI-SPME-GC-FID methods were found to be 10 and 0.3 ng mL−1, respectively. The relative recovery values (for the analysis of 1 µg mL−1 nicotine) were found to be 91–110% for EE-DI-SPME and 75–105% for DI-SPME. The enrichment factors for DI-SPME and EE-DI-SPME sampling were obtained as 38,734 and 50,597, respectively. The results indicated that EE-SPME was more efficient for quantitation of nicotine in biological fluids. The developed procedure was successfully carried out for the extraction and measurement of nicotine in real plasma and urine samples.
