Abstract

The utility of zero-order and first- and second-derivative ultraviolet (UV) spectrophotometry for the identification of benfluralin, trifluralin, isopropalin and oryzalin is discussed. These four herbicides were determined by zero-order and first-derivative UV spectrophotometry, with linear calibration graphs established between 50 and 100 concentration units and limits of detection ranging from 1 to 7 micrograms ml-1. The application of these techniques to the residue analysis of fortified soils and niebe and peanut leaves is described. Trifluralin residues were found to be 6.7, 8 and 1.7 micrograms ml-1 in samples of fortified soils, niebe leaves and peanut leaves, respectively. Isopropalin residues were found to range from 62 to 154 micrograms ml-1 in samples of fortified niebe leaves.
