Resumen:
The fluorimetric signal produced by bentazone retained in selected solid surfaces was investigated. Among the different tested supports, only a microporous nylon membrane produced the desired signal. The quantitative study was carried out by second-order calibration using parallel factor analysis, allowing the determination in a highly interfering medium. A detection limit of 0.4 ng mL−1, a prediction relative error of 8%, and a sample frequency often samples per hour were obtained in spiked natural waters using green analytical chemistry principles.
