An osmium (Ⅷ) oxide solution that had been used for sample preparation for electron microscopy was processed by ozonation and then treated with a 0.1 mol/L solution of sodium hydroxide. An apparatus was assembled such that a systemic series of mechanical and chemical operations was performed to regenerate osmium (Ⅷ) oxide. By optimizing the operating parameters of the apparatus, a solution with osmium (Ⅷ) oxide content of 2.0%(w/v) or higher was produced. The generated osmium (Ⅷ) oxide was found to be reusable for sample preparation for electron microscopy.
