Analysis of trifluralin, methyl paraoxon, methyl parathion, fenvalerate and 2,4-D dimethylamine in pond water using solid-phase extraction

A method was developed for the simultaneous extraction of trifluralin, methyl paraoxon, methyl parathion, fenvalerate, and 2,4-D dimethylamine salt in pond water using a solid-phase C₁₈ column. After elution from the C₁₈ column, the eluate was analyzed on a capillary gas Chromatograph equipped with an electron-capture or flame photometric detector.
