| Popis: | An improved quick, easy, cheap, effective, rugged, and safe (QuEChERS) method combined with high-performance liquid chromatography (HPLC) coupled to diode array detection was established for the determination of fomesafen and quizalofop-p-ethyl in beans. It is simple and efficient and can be used in most laboratories. This method optimizes four chromatographic conditions, namely, mobile phase, mobile phase ratio, flow rate, and detection wavelength. The effects of extraction agent, extraction dose, extraction time, NaCl amount, and adsorbent on the pretreatment effect were studied. The recoveries were high (92.4–117.8%), and repeatability was good (relative standard deviation [RSD] ranged from 0.35 to 4.36%). The standard solutions ranged from 0.1 to 25 ?g/mL. The detection limits of fomesafen and quizalofop-p-ethyl were 0.005 and 0.003 mg/kg, respectively. |
