It is significantly expected to develop a simple, sensitive, stable, and on-site method for detecting carbendazim. In this work, the first organic fluorescent sensor for carbendazim was designed and synthesized based on a crown ether-bridging tetra-cyanostilbene macrocycle. This macrocycle exhibited dark-blue fluorescence in THF-H<sub>2</sub>O (5:95) solution, which was transformed into bright-blue fluorescence after sensing carbendazim. High sensing selectivity for carbendazim was observed among 24 kinds of pesticides and ions. The detection limit was as low as 4.22 × 10<sup>-8</sup> M. The sensing mechanism was deduced as two carbendazim molecules being encapsulated in the macrocyclic cavity based on multiple hydrogen bonds, π-π stacking, and hydrophobic action, resulting in stronger rotation restriction of aromatic groups and then higher fluorescence emission.

In soils, neither PE nor PVC was detected in significant amounts.

However, because of their intrinsic non-polar properties, only moderate detection sensitivity can be achieved in the mass spectrometric detection of PAHs. In this work, we presented a novel electrochemically assisted derivatization nano-electrospray ionization mass spectrometry (ECAD-nESI-MS) method to permit the rapid and ultrasensitive analysis of PAHs in complicated samples. In ECAD-nESI-MS, the in situ electrochemical derivatization of PAHs with pyridine and the electrospray ionization are simultaneously activated by applying a high voltage onto the Pt electrode. Notably, the derivatization takes advantage of the inherent electrochemical aspect of electrospray ionization, that is, the electrooxidation of substrates in the positive-ion mode, thus requiring no extra electrochemical cell and potentiostat. Through the electrochemical derivatization of PAHs into the corresponding pyridinium ions, the ECAD-nESI-MS method achieved remarkably improved detection sensitivity, where the limit of detection (LOD) is 3~10 times lower than the state-of-the-art atmospheric pressure chemical ionization mass spectrometry (APCI-MS) and gas chromatography mass spectrometry (GC-MS).

High-intensity ultrasound-assisted extraction (HIUS) was evaluated by varying key processing parameters such as molar ratio, solid-to-liquid ratio (S/L), added water, extraction time, and ultrasound power. Results showed that both molar ratio and added water had a significant impact on extraction efficiency. The addition of water to NADES was crucial in reducing viscosity and enhancing anthocyanin solubility, thereby improving mass transfer. However, excessive water led to decreased extraction yields, likely due to the disruption of hydrogen bonds within the NADES system. The extraction time and ultrasound power proved to be critical factors, as prolonged extraction periods and high power resulted in the degradation of anthocyanins. This study concluded that NADES yielded promising results for anthocyanin extraction. The optimal anthocyanin extraction conditions for açaí (132.20 mg/100 g) were a 1:2 molar ratio, 1:120 S/L, 30% added water, 5 min extraction, and 600 W power. For mangosteen pericarp, the optimal anthocyanin extraction conditions (58.81 mg/100 g) were a 1:2 molar ratio, 1:120 S/L, 30% added water, 5 min, and 1200 W power. For purple yam, the optimal anthocyanin extraction conditions (25.95 mg/100 g) were a 1:3 molar ratio, 1:120 S/L, 20% added water, 5 min, and 1200 W power. Additionally, the NADES-extracted anthocyanins demonstrated good stability across a range of pH values. Liquid chromatography coupled with electrospray ionization and tandem mass spectrometry (LC-ESI-MS/MS) analysis revealed variability in phenolic profiles, while açaí and mangosteen pericarp showed diverse bioactive compounds, including isorhamnetin and epicatechin.
