A liquid chromatographic procedure has been developed for the determination of carbaryl, a phenyl-N-methylcarbamate, and its
main metabolite 1-naphthol, using a C18 column (250mm×4.6mm) with a micellar mobile phase and fluorescence detection
at maximum excitation/emission wavelengths of 225/333 nm, respectively. In the optimization step, surfactants sodium dodecyl
sulphate (SDS), Brij-35 and N-cetylpyridinium chloride monohydrate, and organic solvents propanol, butanol, and pentanol were
considered. The selected mobile phase was 0.15M SDS-6% (v/v)-pentanol-0.01M NaH2PO4 buffered at pH 3. Validation studies,
according to the ICH Tripartite Guideline, included linearity (r > 0.999), limit of detection (5 and 18 ng mL−1, for carbaryl and
1-naphthol, resp.), and limit of quantification (15 and 50 ng mL−1, for carbaryl and 1-naphthol, resp.), with intra- and interday
precisions below 1%, and robustness parameters below 3%. The results show that the procedure was adequate for the routine
analysis of these two compounds in water, soil, and vegetables samples. [-]
