“…3A shows that the Fe 3 O 4 particles synthesized by an in situ co-precipitation gave limited extraction recovery of the analytes, while the extraction performance of the magnetic cork composites was higher than that of the unmodified cork, which is due to the presence of nanoparticles. 40 Therefore, the use of the magnetic cork composite as a sorbent provided better results for the subsequent work in this study. Also, cork containing magnetic particles may alter its specific properties and thus have higher sorbent performance.…”

It is a challenge to research and develop silicon surfactants with good acid and alkali stability. In the present paper, methylpropenyl polyether modified nonionic silicone surfactant (MPNTS), an alkali-resistant and hydrolysis-resistant silicone surfactant, was synthesized by hydrosilylation of 1,1,1,3,5,5,5-heptamethyl trisiloxane (MDHM) and methylpropenyl polyether (EO(7)). The polyether segments are grafted onto the main chain of organosilicon heptamethyl trisiloxane at a molar ratio of 1:1.05 (n(Si-H):n(C=C)). To evidence product formation, the MPNTS were analyzed by FT-IR and 1H NMR spectroscopy. The surface tension of NPNTS is 18.68 mN/m, and the CMC value is 78 mg/L by a contact angle tester. MPTNS shows hydrolytic stability and maintains that it could keep surface activity after standing for 60 days at pH = 7–10. The compatibility performance analysis shows that MPNTS has good compatibility and synergy with cationic, anionic, and nonionic surfactants, and it reveals the application prospects in daily chemicals, agricultural adjuvants, and other products.

“…These solvents are green and easily prepared by mixing two or three individual components which can be associated with each other through a hydrogen bond interaction [24,25]. Up to now, the application of DESs has been reported in the determination of OPPs in sample preparation methods in various samples including vegetables [26], honey and fruit samples [27], water and soil samples [28], etc.…”

Herein, a deep eutectic solvent (DES)‐based miniaturized pressurized liquid extraction in combination with DES‐based dispersive liquid–liquid microextraction (DLLME) was developed for the extraction of organophosphorus pesticides (parathion–methyl, triazophos, parathion, diazinon, and phoxim) from egg powder samples prior to their analysis by a high‐performance liquid chromatography‐diode array detector. In this work, first, the analytes' extraction was done by a pressurized liquid phase extraction for effective extraction of the analytes from the solid matrix, and then they were concentrated on a DLLME for more concentration of the analytes to reach low limits of detections. The use of DESs was done in both steps to omit the use of toxic organic solvents. Satisfactory results including high extraction recoveries (74–90%), great repeatability (relative standard deviations equal or less than 4.3% and 5.3% for intra‐ and inter‐day precisions), and low limits of detection (0.11–0.29 ng/g) and quantification (0.38–0.98 ng/g) were attained under the optimum conditions. Lastly, the suggested approach was utilized for the determination of the studied pesticides in various egg powder samples marketed in Tabriz, Iran.
