Residue Dynamic Analysis of Imazalil in Rambutan by RP-HPLC with Solid-Phase Extraction
摘要
Abstract
A reversed-phase high performance liquid chromatographic method with solid-phase extraction was proposed for the residue dynamic analysis of imazalil in rambutan.The analyte was separated on a Shim-pack VP-ODS(150 mm × 4.6 mm,5μm) using a mobile phased composed of a mixture at a volume ratio of 75:25 of methanol and acidic Na2H2PO4 solution approximately at pH 5(adjusted with 85% phosphoric acid) at a flow rate of 0.85 mL/min,and detected at 229 nm.The injection amount was 20 μL.An excellent linearity of imazalil in the range of 15.0-960.0 μg/L was achieved(r =0.9994).The detection limit was 5.0 μg/L.The average spike recovery rates were in the range of 86.4%-104.5% with relative standard deviation of 0.84%-2.87%.The method was fast,simple,and applicable for the determination of imazalil residue in rambutan.关键词
