Sensitive spectrofluorometric determination of vanadium with sodium 1,2-dihydroxyanthraquinone-3-sulfonate in cationic micellar medium García Campaña, Ana María Alés Barrero, Fermín Román Ceba, Manuel Spectrofluorometry Sodium 1,2-dihydroxyanthraquinone-3-sulfonate Vanadium determination Micellar medium A spectrofluorometric method is described for the determination of vanadium(V) based on its complexation reaction with sodium 1, 2-dihydroxyanthraquinone-3-sulfonate in presence of hexadecyltrimethylammonium bromide. The fluorescence is monitored at 607nm with excitation at 505nm. The experimental variables and interferences in this determination have been studied. The detection limit is 3.0ng ml-1 and the linear range is between 10 and 1000ng ml-1. The method has been applied to the determination of vanadium in clams and seawater with satisfactory precision. 2014-07-01T11:16:59Z 2014-07-01T11:16:59Z 1996 info:eu-repo/semantics/article García Campaña, A.M.; Alés Barrero, F.; Román Ceba, M.
