【摘要】：本文建立了用高效液相色譜-二極管陣列檢測器法(HPLC-DAD)測定飼料樣品中苯基脲類農(nóng)藥殘留分析方法。測定中使用C_(18)柱(250 mm×4.6 mm,5μm),流動相為乙腈和水,采用溶劑梯度結(jié)合波長和流速梯度等洗脫技術(shù)。實驗結(jié)果表明:6種農(nóng)藥在20 min內(nèi)實現(xiàn)了基線分離,線性相關(guān)系數(shù)≥0.9990,檢出限為0.2~1.0 mg/L,平均回收率為83.6%~93.9%,其相對標(biāo)準(zhǔn)偏差(RSD)為1.24%~4.64%,該方法操作簡單,靈敏度高,結(jié)果準(zhǔn)確可靠。
[Abstract]:A method for the determination of phenylurea pesticide residues in feed samples by high performance liquid chromatography-diode array detector (HPLC-DAD) was established. The determination was performed on a 250 mm 脳 4.6 mm ~ (5 渭 m) column with a mobile phase of acetonitrile and water. Solvent gradient combined with wavelength and flow rate gradient were used to elucidate. The experimental results showed that the baseline separation of 6 pesticides was achieved within 20 min. The linear correlation coefficient is 鈮，
