Identification of the Fluorescent Photoproducts: Analysis of Two Phenylureas by Photo-Induced Fluorescence (PIF) and GC-MS

摘要

Quantitative analysis of diflubenzuron (DFB) and fenuron (FEN) pesticides was successfully performed using photo-induced fluorescence (PIF) methods. The analytical conditions were optimized for the determination of traces of these pesticides in Senegalese natural water samples. Mean recoveries were satisfactory, ranging between 80 and 120%. Also, gas chromatography-mass spectrometry (GC-MS) was combined with the PIF methods, in order to identify the formed fluorescent photoproducts.
