摘要
本文运用气相色谱法,测定了白芍根中敌百虫的残留量。样品用甲醇提取,在4%PEG-2M/ChromosorbW(AW)-DMCS(60~80目)柱上,检测敌百虫的残留,它的最小检出浓度为0.005ppm。
gas chromatographic(GC) method is described for the determination of dipterex in the root of paeonia. Samples are extracted with methanol. Residues of dipterex are determined directly on a column of 4% PEG-ZM coated on 60~80 mesh Chromosorb W(AW)-DMCS support.The detection limit for dipterex is 0. 005ppm.
