Determination of agrochemical combinations in spiked soil samples

Quantitative determination of combinations of the agroghemicals: propham, chlorpropham, diflubenzuron, cypermethirn and tetramethrin from spiked soil is reported. Method involves ultrasonic extraction of agrochemicals with acetone, separation of samples by means of reversed-phase thin-layer chromatography and quantirfication by slit-scanning densitometry. Computer-assisted optimization was used to select the optimum mobile phase composition.
