Abstract This paper reports volatilization behavior of RuO4 from nitric acid medium using UV–Vis spectroscopy. Ruthenium (III) solution was oxidized to Ru (VIII) using potassium metaperiodate. The absorption peak of RuO4 at 385 nm was used to measure Ru(VIII) concentration in solution. The volatilization kinetics has been studied at different temperature and used to derive rate constant and activation energy values. Almost 82% Ruthenium (VIII) has been volatilized from nitric acid medium at 70 °C whereas it is only 15% at 25 °C. Effect of different parameters like temperature, potassium metaperiodate concentration and nitric acid concentration on volatilization has been studied in depth and reported in this paper.

RuO4在硝酸介质中的挥发行为研究

摘要 本文报告了使用紫外-可见光谱法从硝酸介质中挥发 RuO4 的行为。使用偏高碘酸钾将钌 (III) 溶液氧化成 Ru (VIII)。RuO4 在 385 nm 处的吸收峰用于测量溶液中的 Ru(VIII) 浓度。在不同温度下研究了挥发动力学，并用于推导速率常数和活化能值。在 70 °C 时，几乎 82% 的钌 (VIII) 从硝酸介质中挥发，而在 25 °C 时只有 15%。本文深入研究并报道了温度、偏高碘酸钾浓度和硝酸浓度等不同参数对挥发的影响。
