Abstract

Abstract: Asensitive and selective method for the simultaneous determination of Nb and Ta in alloy steel, which is based on the basic principle of the dual-system and double-wavelength spectrophotometry, has been developed. SAPand 5Br-PADAP were chosen for constructing "the pair of coloured system", and Nb and Ta were quantified by the formulas: △A_Nb =A_{5Br-PADAP,604} - 0.28A_SAF,513 △A_Ta=A_SAF,513 -A_{5Br-PADAP,615} respectively. The present method has a high sensitivity (△ε_Ta = 1.35 ×10⁵, △ε_Nb =1.33×10⁵), and most of common ions do not disturb the determination of Nb and Ta.
