Determination of dinitroaniline herbicides in environmental samples by gas chromatography

Abstract
Simultaneous determination of several dinitroaniline herbicides in environmental samples (soil, plant and air) was performed by gas chromatography with ion trap and nitrogen-phosphorus detection.

Soil was extracted with ethyl acetate on an orbit shaker and plants were extracted with methanol in a Sorvall homogenizer. The plant extract was purified on a Florisil column before gas chromatographic analysis. The dinitroaniline herbicides volatilized from soil were trapped on a Florisil column, eluted with acetone and then analyzed by gas chromatography.

The concentrations of these compounds were determined by gas chromatography with nitrogen-phosphorus detection on a HP-1 capillary column and with ion trap detection on a BP-1 capillary column. Helium was used as carrier gas.

In all cases, the average recoveries were higher than 75%. The limit of detection for these herbicides was, at least, 0.01 μg/g in soil, 0.05 μg/g in plant and 1 ng/l in air with both gas chromatographic methods.

The electrochemical reduction behavior of two dinitroaniline herbicides, Butralin (BN) and Isopropalin (IN), at a mercury electrode is described based on different voltammetric techniques in various buffer solutions at different pH values. The nature of the electrode process has been examined. A reduction mechanism was proposed. Britton–Robinson (BR) buffer of pH 4.0 was found to be best media for the analysis of the compounds. Both standard addition and calibration methods were used for analysis. The detection limits were found to be 6 × 10−8 M (M = mol dm−3) for BN and for 1.5 × 10−8 M for IN. A differential pulse polarographic method was developed for the determination of the herbicides in grains and soils as well as water samples.

这个项目我们也没有分析过，有空试试，谢谢我在故我思(hotdoglet)版主。

谢谢版主的帮助啦！非常感谢呀！
