Abstract
A spectrofluorometric method is described for the determination of van adium(V) based on its complexation reaction with sodium 1,2-dihydroxya nthraquinone-3-sulfonate in presence of hexadecyltrimethylammonium bro mide. The fluorescence is monitored at 607 nm with excitation at 505 n m. The experimental variables and interferences in this determination have been studied. The detection limit is 3.0 ng ml(-1) and the linear range is between 10 and 1000 ng ml(-1). The method has been applied t o the determination of vanadium in clams and seawater with satisfactor y precision.
