In the 0.025~ 0.18 mol/ L sulfuric acid solution, niobium (V) and amonium molybdate form the molybdoniobate heteropoly acid complex, then in 1.44~2.1 mol / L sulfuric acid medium, the ion-associate complex of molybdoniobate heteropoly species and BRB was formed in the presence of polyvinyl alcohol. The ion-associate exhibits maximum absorptivity at 580 nm, its apparent molar absorptivity was found to be 1.9 × 106 L ·mol-1 ·cm-1. Beer's law is obeyed in the range of 0 to 1.8 μg / 25 ml for Nb ( V ) . The molar ratio of Nb ( V ) to BRB in ion-associate was established to be 1 '. 3 by equilibrium movement method. The complex is supposed to be a ion-association complex with the possible formula BRB3 ·[NbMo12O3-40] . The proposed method has been used for the determination of trace niobium (V ) in steel and some ores with satisfactory results.
