Malathion is an insecticide in the chemical family known as organophosphates. Therefore, a 4 min desorption time and 230°C desorption temperature were used as optimum condition in all experiments. SWCNT-coated fibres were prepared according to the previous study [15]. Since the best peak shapes were obtained at 230°C, this temperature was selected as the desorption temperature. Potential factors affecting the extraction efficiency were optimized, and the analytical performance of the developed SWCNT-coated fibre was compared with that of commercial PDMS fibre, which was frequently used for determination of OPPs in different matrices [1, 19–21]. Therefore, a large quantity of them is consumed in both daily life and pharmaceutical industries. 9 The results are demonstrated in Figure 1. The LODs for the analytes were determined in the range of 0.3 to 0.5 ng g−1 which is better or comparable with that of reported methods. 2020 Oct;20(4):84. doi: 10.3892/ol.2020.11945. Comparison of the extraction yields of commercial PDMS and SWCNT fibre for 75 ng g−1 OPPs was carried out under the optimal HS-SPME condition of each fibre, and the results are represented in Figure 3. 1982;2(1):5-73 The results proved the feasibility of the fibre preparation method. Int J Environ Res Public Health. For sample preparation, 1 g of each sample was transferred into a 25 mL HS-SPME glass vial containing 0.5 g of NaCl and 100 μL of methanolic solution of caffeine (I.S., 1 μg mL−1). ) and was determined by spiking serially diluted analyte standards into blank samples. The fibre was then retracted, removed from the vial, and placed immediately into the injector of the GC system. These advantages of SWCNT fibre expand the HS-SPME-GC application range toward higher-boiling compounds and prolong the fibre lifetime. Epub 2018 Apr 12. In addition, a comparative study between the single-walled carbon nanotubes and a commercial polydimethylsiloxane fibre for the determination of target analytes was carried out. Sevin, an insecticide containing the neurotoxin carbaryl, is best for corn earworms, cutworms and Japanese and other beetles. The developed method showed good performance. Of these insecticides parathion andmost detail Most authors agree on the positive effect of salt addition to the sample for improving the extraction efficiency [20, 22]. So optimizing the extraction temperature is necessary. Would you like email updates of new search results? Therefore, 0.5 g of NaCl per 20 mL of sample was selected as the optimum condition in the following experiments. The main difference between the susceptible and resistant strains was the superior ability of the latter to degrade malathion to malathion monocarboxylic acid (O, O-dimethyl S-(l-carboxy-2-ethoxy-carbonyl)ethyl or S-(2-carboxy-1 Parathion binds tightly to soil particles and has little or no potential for groundwater contamination. Selected ions used for the quantification and qualification of target analytes by GC-MS (SIM mode). On the other hand, pesticides are often used in order to improve productivity and profit margins in the production of medicinal plants. − Under the optimal conditions, broad calibration curves were obtained with the linearity in the range between 0.30–200 ng mL −1. Therefore, pesticide residues in herbal medicinal materials become pitfalls in safety and present obstacles to be acknowledged by the international community.
