PHOTOCALOMETRIC DETERMINATION OF NIOBIUM,

Abstract

A method is given for the photocalimetric determination of niobium, with the aid of dioxide -3.4 - phenol - 4 azobenzine, which permits the determination of niobium in the presence of significant quantities of tungsten, vanadium, nickel, silicon, rare earth materials and elements, aluminum cobalt, chrome, etc. The determination of niobium also does not interfere with the presence of a three-fold surplus of titanium and a five fold surplus of tantalum. The maximal error does not exceed 4.1%. A method was devised for varifying analytically, artificial mixtures of approximate composition with some alloys and niobium containing ores. (Author)
