在稀硫酸介质中，铌（V）灵敏催化溴酸钾氧化氛磺酚S褪色反应，据此建立了催化动力学光度法测定铌的新方法。线性范围为0．005－0．1mg／L，检测限2.9μg／L。本法准确、灵敏、简便，已用于合金钢中微量铌的测定。
In dilute sulfuric acid medium, niobium (V) sensitive catalytic potassium bromate oxidation of the phenol sulfone S fading reaction, thus establishing a catalytic kinetic spectrophotometric determination of niobium new method. Linear range of 0.005-0.1mg / L, detection limit of 2.9μg / L. This method is accurate, sensitive and simple and has been used for the determination of trace niobium in alloy steel.
