General description

Nitric acid (HNO3) is a highly corrosive strong mineral acid. 10%(v/v) nitric acid solution is useful for cleaning laboratory glasswares.[1]

Application

Nitric acid (HNO3) may be used for the removal of transition metal catalyst from the single-walled carbon nanotubes (SWNTs) during the purification of SWNTs.[2] It may be used in the trace level detection of Pb and Cd in aqueous samples by flame atomic absorption spectrometry.[1]

Caution

Due to the chemical properties of nitric acid, fuming 100%, it is possible, that nitrogen oxides may form when it is exposed to light.

The unique physical and chemical properties of nanomaterials have led to their increased use in many industrial applications, including as a paint additive. For example, titanium dioxide (TiO2) engineered nanoparticles (ENPs) have well-established anti-UV, self-cleaning, and air purification effects. Silver
