摘  要:
Using chromatographic column of Hypersil C18 (150 mm×4.6 mm, 5 μm), methanol-water (volume ratio of 3∶1) as mobile phase, flow rate 1.0 mL/min, detection at 254 nm, the content of 50% pirimiphos-methyl EC was determinated. The coefficient of variation was 0.34%, the average recovery rate was 99.6%.
