“…In order to plot the calibration curve, different TAR solutions were evaluated in the range of 0.25 to 10 mmol L −1 using acetonitrile as a solvent for TAR quantification. The limit of detection (LOD) and limit of quantification (LOQ) were determined using the first point of the calibration curve, as reported in previous studies [ 29 , 30 , 31 ].…”

This study presents a new optical sensor for tartrazine (TAR) quantification developed using a molecularly imprinted polymer (MIP) as the recognition element, with optical fiber serving as the supporting substrate. The fiber surface was functionalized with 3-(trimethoxysilyl)propyl methacrylate (MPS), and the fiber was coated with MIP using the precipitation polymerization method. The analysis of MIP immobilization on the functionalized optical fiber (FF) was conducted through the use of scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) techniques. Experimental parameters, such as contact time and fiber length, were adjusted in order to obtain the highest sensitive response signal for the functionalized optical fiber (FF-MIP). The fiber sensor, FF-MIP, exhibited a relatively higher response signal for tartrazine compared to other interfering dyes. The rapid and total desorption of the analyte from FF-MIP allowed the immediate reemployment of FF-MIP, which also presented an acceptable repeatability for the reflectance signal. The imprinting factors for the studied dyes were between 0.112 and 0.936 in front of TAR, 1.405, and selectivity factors were between 1.501 and 12.545, confirming the sensor selectivity. The FF-MIP sensor was successfully applied for tartrazine quantification in real water samples, where it yielded satisfactory results comparable to those of the HPLC reference method.

“…They are known as green solvents which could be used as extraction solvents instead of the common toxic organic solvents such as carbon tetrachloride and dichloromethane. DESs can be easily synthesized by mixing a hydrogen bond acceptor (HBA) and one or two hydrogen bond donor (HBD). − A wide range of HBDs and HBAs have been used to make DESs. These are composed of a mixture of safe, cheap, renewable, and biodegradable organic compounds that are capable of associating with each other through hydrogen bonding and forming a compound that has a melting point far below that of either component .…”

Thermal processing techniques are often accompanied by the production of many harmful compounds such as heterocyclic aromatic amines (HAAs). To protect human health, an efficient and environmentally friendly method, namely, homogeneous liquid−liquid microextraction (HLLME), was investigated. This method is based on a surfactant-assisted hydrophobic deep eutectic solvent for the determination of HAAs in edible fried insect samples prior to their analysis by high-performance liquid chromatography coupled with UV detection. A hydrophobic deep eutectic solvent (as extraction solvent) was synthesized using decanoic acid as a hydrogen bond donor and tetrabutylammonium bromide (TBABr) as a hydrogen bond acceptor and then characterized by Fourier transform infrared (FTIR) spectroscopy. The surfactant was used as the emulsifier and induces mass transfer, resulting in an increasing extraction efficiency of the proposed method. Various factors affecting the extraction performance were investigated and optimized. A matrix-match calibration method was used to analyze HAAs in high heat-treated edible fried insect samples. Under optimized conditions, the proposed method showed good linearity (R 2 ≥ 0.99) with satisfactory limits of detection and satisfactory reproducibility with relative standard deviation of less than 10.0%. Furthermore, the procedure greenness was assessed using the Analytical Eco-Scale. This paper represents the first application of HLLME based on a surfactant-assisted hydrophobic deep eutectic solvent to analyze HAAs in edible fried insect samples.

“…Aromatic amines are extensively used as raw materials or as intermediates in the manufacturing of industrial chemicals such as pharmaceuticals, agrochemicals, polymers, azo dyes, and rubbers. − Aromatic anilines are classified as an important class of environmental pollutants because they are highly toxic to humans and are potential carcinogens. − Due to their high solubility in water, they are easy to penetrate into soil and pollute groundwater, where they have been found at trace levels (<10 μg/L). − For this reason, in this last period, an increasing attention has been devoted to the development of new, reliable, highly selective, sensitive, and rapid analytical methods for their detection, leading to the publication of numerous reports in this field, − exploiting in particular gas chromatography (GC) techniques. − However, direct determination of aromatic aniline isomers using GC techniques is still difficult due to their polar nature; then, aromatic aniline isomers are usually first derivatized and then determined by GC in combination with mass spectrometry (MS) techniques. − Derivatization greatly increases the analysis time and its cost, and it makes use of great amounts of organic solvents, becoming a source of environmental pollution.…”

In this work, the fabrication, synthesis, and characterization of a new stationary phase based on an amphiphilic pillar[6]arene (P6A-C10-2NH2) for gas chromatographic analyses are reported. The gas chromatography (GC) column prepared with P6A-C10-2NH2 stationary phase exhibited a medium polarity, an efficiency of 3219 plates/m, and unmatched resolving capabilities toward chloroaniline, bromoaniline, iodoaniline, and toluidine isomers. Furthermore, the P6A-C10-2NH2 column showed excellent repeatability with maximum relative standard deviations equal to 0.02, 0.07, and 2.56% for run-to-run, day-to-day, and column-to-column, respectively, demonstrating a great potential as a new stationary phase in separation science.
