“…The impact of their residue in the agricultural products and regarding human exposure needs to be explored. Thus, quantitation of individual enantiomers in those products will provide a more adequate basis for assessing the risk of utilizing TF and TN .

“…Triazole fungicides are one of the most efficient systemic fungicides that also have low toxicity. 1 A large number of triazole fungicides have stereogenic centers in their molecular structure, and some of their metabolites are also chiral. These fungicides are usually marketed, and as racemate products, even the enantiomers may have different environmental behavior, metabolic rate, and toxicity.…”

A supramolecular solvent composed of decanol in tetrahydrofuran/water was utilized for the simultaneous microextraction of chiral triadimefon and triadimenol in beer samples. Supramolecular solvents are nanostructured amphiphilic liquids that contain aqueous cavities, and the size of those cavities can be adjusted by the ratio of decanol, tetrahydrofuran, and water. The target analytes were mixed into the matrix sample and extracted in the supramolecular solvent phase, which was followed by separation and quantification by chiral liquid chromatography-mass spectrometry. The influences of some analytical parameters and matrix components were all examined. Under the optimized conditions, the method detection limits were in the range of 0.24 to 0.98 μg L (at a signal/noise of 3), with relative standard deviations between 1.6 and 5.7%. The linearities of the calibration plots were between 0.5 to 50 (triadimenol) and 1.0 to 100 μg L (triadimefon). When this method was applied to a spiked beer sample, the recoveries ranged from 84 to 100%.

“…While, adsorption process is cheap, in situ, easy, fast and novel approaches for the decontaminate wastewaters [14][15][16][17][18][19]. The adsorption-based processes are interest to implement the most of these considerations and requirements [20,21]. Therefore, search and design a novel adsorbent in this method is important.…”

Multiwalled carbon nanotubes (MWCNTs) functionalized with (N-3-phenylallaylidene)-N'-trimethoxysilylpropylethane-1, 2-diamine (PATMSPEDA) were prepared and subsequently the MWCNTs-PATMSPEDA-Pd-NPs nanohybrids with high shape selectivity and high specific surface area have been prepared by single step synthesis of Pd nanoparticles (Pd-NPs) loaded on MWCNTs-PATMSPEDA. These materials were characterized by different techniques such as XRD, SEM, FT-IR and TGA-DTA and subsequently were used for the simultaneous ultrasoundassisted removal of erythrosine (ER) and sunset yellow (SY) dyes from aquaes solution. The influences of important variables such as initial dyes concentration, adsorbent dosage, pH and sonication time on the efficiency of ultrasound-assisted removal process were investigated by central composite design (CCD) and the optimization conditions were obtained 4.39 and 4.33 mg L-1 of ER concentration, 11.76 and 11.90 mg L-1 of SY concentration, 0.02 and 0.019 g adsorbent mass, 7.0 and 7.0 for pH value and 3.88 and 3.75 min sonication time for MWCNTs-PATMSPEDA and MWCNTs-PATMSPEDA-Pd-NPs, respectively. The artificial neural network (ANN) model was used for building up to construct an empirical model to predict the understudy dyes removal behavior onto these adsorbents and the obtained results have good agreement with experimental data. The absolute average deviations (AADs) of ER and SY dyes adsorption by MWCNTs-PATMSPEDA are 0.62% and 0.58%, and the determination coefficient (R 2) values are 0.971 and 0.978, respectively. Also, the AADs of ER and SY dyes adsorption by MWCNTs-PATMSPEDA-Pd-NPs are 0.48% and 0.34%, and the R 2 values are 0.971 and 0.972, respectively. Finally, it was found that the equilibrium isotherm of adsorption process follows the Langmuir isotherm. From the Langmuir isotherm, maximum monolayer capacity (q max) were obtained to 30.58 and 38.76 mg g −1 and 55.25 and 59.17 mg g −1 at optimum conditions for ER and SY removal onto MWCNTs-PATMSPEDA and MWCNTs-PATMSPEDA-Pd-NPs, respectively.
