钌的催化动力学分析法颇多,但检出限低于10~(-9)g/L级的甚少。Alekseeva等基于Ru(Ⅲ)对IO_4~-氧化[Fe(phen)_3]~(2+)反应的催化作用,建立了一个检出限和测定范围分别为5×10~(-9)g/L和10—140×10~(-9)g/L Ru的催化电位法。Rysev等利用Ru(Ⅲ)-IO_4~--金莲橙OO催化褪色体系可测定2×10~(-9)g/L的Ru。
Ruthenium catalytic kinetic analysis of a lot, but the detection limit of less than 10 -9 (g) / L level very little. Based on the catalytic effect of Ru (Ⅲ) on the reaction of [Fe (phen) _3] 2+ with [Fe (phen) 3] 2+, Alekseeva et al. Established a detection limit and determination range of 5 × 10 -9 g / L and 10-140 × 10 -9 g / L Ru by catalytic potentiometry. Rysev and other use of Ru (Ⅲ) -IO_4 ~ - lotus Orange OO catalytic fading system can be determined 2 × 10 -9 g / L of Ru.
