研究了在紫外光激发下,水溶液中镨离子的荧光光谱。在217nm光激发下,酸介质中的Pr~(3+)于240和278nm处产生荧光。据此,建立了纯稀土氧化物试样中微量镨的测定方法。
The fluorescence spectra of praseodymium ion in aqueous solution were studied under UV excitation. At 217 nm light excitation, Pr ~ (3+) in the acid medium fluoresces at 240 and 278 nm. Based on this, a method for the determination of trace praseodymium in pure rare earth oxide samples was established.
