Abstract
A new method is described to analyse the binary mixture of folpet and fenamiphos, using the first derivative spectrophotometry obtained by m athematical treatment of the data. Calibration graphs were linear betw een 1.0 to 15.0 mug.mL-1 of folpet and between 1.2 to 27.9 mug.mL-1 of fenamiphos. The method has been applied for determining both pesticid es in commercial formulations and groundwater at ng.mL-1 levels after a preconcentration step with C18.
