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).

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.
