On-line submicellar enhanced fluorometric determination of Se(IV) with 2,3-diaminonaphthalene

The flow injection (FI) analytical determination of Se(IV) with 2,3-diaminonaphthalene (DAN) was assayed employing enhanced fluorometric detection. The different variables affecting the reaction rate between Se(IV) and DAN were studied in batch mode, and the best conditions for the 4,5-benzopiazsele...
