Zirconium(Ⅳ)-based metal-organic framework for determination of imidacloprid and thiamethoxam pesticides from fruits by UPLC-MS/MS

New strategies for identifying and masking the bitter taste in traditional herbal medicines: The example of Huanglian Jiedu Decoction

“…Gas 1 and Gas 2 were both 55 Psi, the IS was 4500 V, the ionization temperature was 600°C, the curtain gas was 25 Psi, the collision voltage was 25 V, and the chamber injection voltage was 15 V. Data analysis was performed using AnalystTM1.6 software and MultiQuantTM3.0 software (American AB SCIEX). Eventually, the compounds with |ΔPPM | < 15.0 were derived ( Xu et al, 2021 ).…”

A novel magnetic metal–organic framework absorbent for rapid detection of aflatoxins B1B2G1G2 in rice by HPLC-MS/MS

“…This result was basically consistent with the literature data. 42 The XRD patterns of Fe 3 O 4 and Fe 3 O 4 @UiO-66-NH 2 are shown in Fig. 2(d).…”

A comprehensive review on the pretreatment and detection methods of neonicotinoid insecticides in food and environmental samples

“…Due to the high surface area, large pore volume, and excellent stability in the water and acid conditions, UiO-66 ( Cao et al, 2018 ) was used as the dSPE sorbent to extract IMI, ACE, THI, THX, CLO in water samples. Moreover, the addition of amino groups on UiO-66 (UiO-66-NH 2 ( Xu et al, 2020 )) may increase the electrostatic interactions between the sorbent and analytes, allowing efficient extraction of IMI and THX from fruit samples. The amount of adsorbent (≤50 mg) used for dSPE is significantly less than that of the SPE column, and the dSPE also has a satisfactory recovery.…”
