| 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). |
| Application: | Used for the decomposition of organic and inorganic samples for det. of mercury |
| 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. |
