Abstract
The measurement of fluorescence is continuously performed at an excitation wavelength of 521 nm and an emission wavelength of 617 nm. Using a low sample volume of 800 μl, the analytical signal showed a very good linearity in the range 2-60 ng mlâ1, with a detection limit of 0.45 ng mlâ1 and a R.S.D. (%) of 4.22 for 50 ng mlâ1 of V(V) concentration (n = 10). The sensor showed both a good selectivity, which could also be increased by the addition of EDTA and Fâ as masking agents, and applicability to the determination of V(V) in waters, physiological samples (serum and urine) and mussel tissues.
