Spectrofluorimetric determination of beryllium in rocks, alloys and steels with nuclear fast red

Abstract

A spectrofluorimetric method is described for the determination of trace amounts of beryllium, based on its reaction with Nuclear Fast Red. The detection limit is 3 ng ml^–1 and the method can be used to determine between 10 and 80 ng ml^–1 of beryllium. The stoicheiometry of the complex is 1 : 1. The method has been satisfactorily applied to the determination of beryllium in rocks, alloys and steels.
