前言钌的极谱法研究已有不少报道,但实际应用较少。Ru(Ⅲ)在盐酸或硫酸体系中的催化极谱波,具有较高的灵敏度,但波高不稳定。Niedrach等研究过Ru(Ⅳ)在高氯酸中的极谱行为。Susic提出在0.9mol/l高氯酸中测定钌。本文采用在HClO_4-NaNO_3-NaClO_4体系中测定钌,在此体系中钌(Ⅳ)在-0.8 V(对SCE)产生一清晰的极谱波,此波比在单一高氯酸底液中的波灵敏。试验了影响极谱
Preface Ruthenium polarographic studies have been reported, but less practical application. The catalytic polarographic wave of Ru (Ⅲ) in hydrochloric acid or sulfuric acid has high sensitivity, but the wave height is unstable. Niedrach et al. Studied the polarographic behavior of Ru (IV) in perchloric acid. Susic proposed the determination of ruthenium in 0.9 mol / l perchloric acid. In this paper, the determination of ruthenium in HClO_4-NaNO_3-NaClO_4 system, ruthenium (Ⅳ) in this system at -0.8 V (SCE) to produce a clear polarographic wave, this wave than in a single perchloric acid bottom liquid wave Sensitive. Experiments affected the polarography
