✦ Synopsis

Separation and determination of carbamate awd wea herbicides by reactioN gas ckromato-gra+hY

The behaviour of a number of carbamate and urea herbicides during thermal degradation in the interior of the gas chromatographic apparatus and during chromatography through a KOH-layered reaction separation column is studied. Methods are developed for the direct gas chromatographic analysis of the herbicidal active substances proximpham, propham, chlorpropham, fenuron, monuron, diuron, monolinuron, linuron, and metobromuron.

Results show that the rapid separation and quantitative determination of these herbicides is possible.
