“…Georgakopoulos et al 34 and Herrmann and Poulsen 35 believe that C 18 was suitable for the purification of some low-fat samples, including cereals and vegetables at a certain dosage. Therefore, referring to the purification method of Li, 36 we mixed adsorbents PSA and C 18 at different additions to study the difference.…”

A new type of mesoionic insecticide triflumezopyrim is mainly used to control rice planthoppers, leafhoppers, etc. In order to study the uptake and translocation characteristics of this new insecticide in rice (Oryza sativa), a method for the detection of triflumezopyrim in rice, soil, and water was established using liquid–liquid extraction and QuEChERS sample pretreatment combined with liquid chromatography–triple quadrupole tandem mass spectrometry. The distribution of triflumezopyrim in rice was investigated after hydroponic treatment and foliar treatment at the concentrations of 2.5 and 5 mg·L–1 within the ranges of 24, 48, and 72 h. The results showed that triflumezopyrim could be absorbed by roots and form a systematic distribution in rice by hydroponic treatment; meanwhile, it could also be absorbed by leaves and transported to the bottom leaves under foliar treatment, but no triflumezopyrim was detected in the roots. Thus, triflumezopyrim exhibited high acropetal translocation within the rice plant. This study provides an important scientific basis for the development of an application strategy of triflumezopyrim to control planthoppers and leafhoppers as well as for the residue detection method and safety evaluation.

“…The samples containing FLU were soil samples collected from different agricultural lands sprayed with flucarbazone pesticide. A 250 g of different soil samples was soaked into 250 mL water and sonicated for 2 h. After filtration, the obtained filtrate was then analyzed by the proposed potentiometric cell and the results were compared to those obtained by the standard liquid chromatography/mass spectrometry (LC-MS/MS) method [6]. In brief, high-performance liquid chromatography (HPLC) (Agilent 6410, USA) coupled with a triple quadrupole mass spectrometer (Agilent, Santa Clara, CA, USA) and an electrospray ionization (ESI) source.…”

“…To check the existence level and the transfer behavior of FLU after use, it is important to find a reliable analytical method to assess this compound. Some methods were reported in the literature for the determination of flucarbazone, such as liquid chromatography/mass spectrometry (LC-MS/MS) [6], gas chromatography [7], high-performance liquid chromatography (HPLC) [8] and bioassay methods [9,10,11]. For herbicide residue assays in soil samples, the plant assay and chemical methods are frequently used.…”

Novel potentiometric solid-contact ion-selective electrodes (SC/ISEs) based on molecularly imprinted polymers (MIPs) as sensory carriers (MIP/PANI/ISE) were prepared and characterized as potentiometric sensors for flucarbazone herbicide anion. However, aliquat S 336 was also studied as a charged carrier in the fabrication of Aliquat/PANI/ISEs for flucarbazone monitoring. The polyaniline (PANI) film was inserted between the ion-sensing membrane (ISM) and the electronic conductor glassy carbon substrate (GC). The sensors showed a noticeable response towards flucarbazone anions with slopes of −45.5 ± 1.3 (r2 = 0.9998) and −56.3 ± 1.5 (r2 = 0.9977) mV/decade over the range of 10−2–10−5, 10−2–10−4 M and detection limits of 5.8 × 10−6 and 8.5 × 10−6 M for MIP/PANI/ISE and Aliguat/PANI/ISE, respectively. The selectivity and long-term potential stability of all presented ISEs were investigated. The short-term potential and electrode capacitances were studied and evaluated using chronopotentiometry and electrochemical impedance spectrometry (EIS). The proposed ISEs were introduced for the direct measurement of flucarbazone herbicide in different soil samples sprayed with flucarbazone herbicide. The results agree well with the results obtained using the standard liquid chromatographic method (HPLC).

“…A simple QuEChERs extraction technique requiring little cleanup and highly selective gas and liquid chromatography with tandem mass spectrometry has been used for analysis of 80 pesticide residues including guadipyr from various matrices [16,17]. The dissipation dynamics of 20% guadipyr suspension was investigated in rice matrices, paddy soil and paddy water, which would help the government to establish the maximum residue limit (MRL) of guadipyr in rice and to provide guidance on proper use of it.…”
