General description
Nitric acid (HNO3) is a highly corrosive strong mineral acid. In HNO3, nitrogen element exhibits +5 oxidation state. 10%(v/v) nitric acid solution is useful for cleaning laboratory glasswares. Reaction of HNO3 with various original and synthetic mineral dust/mineral oxide surfaces was studied in a low-pressure Knudsen reactor operating at 298K.
Application
Nitric acid (HNO3) may be used in the following studies:
• Oxidation of multiwalled carbon nanotubes (MWCNTs).
• Removal of transition metal catalyst from the single-walled carbon nanotubes (SWNTs) during the purification of SWNTs.
• Trace determinations of Pb and Cd in aqueous medium by flame atomic absorption spectrometry.
• Preparation of lead dioxide (PbO2).
Used for the decomposition of organic and inorganic samples for det. of mercury
