Physicochemical characteristics

The specific gravity is 1.368-1.486 when the temperature is 20. It is strong oxidizer, a kind of strong acid with strong causticity. It is easy to be decompounded when heated. Safety requirement

 

For its strong oxidizer, it should not be touched by organic substance. For its strong causticity, protective articles should be worn. The fire caused by nitric acid (cone) should be extinguished by sandy soil, carbon dioxide and washed by large amount of water. At the same time, toxicosis of nitrogen oxide should be avoided.

 

 

 

Elemental analysis

 

 

In elemental analysis by ICP-MS, ICP-AES, GFAA, and Flame AA, dilute nitric acid (0.5 to 5.0 %) is used as a matrix compound for determining metal traces in solutions. Ultrapure trace metal grade acid is required for such determination, because small amounts of metal ions could affect the result of the analysis.

 

It is also typically used in the digestion process of turbid water samples, sludge samples, solid samples as well as other types of unique samples which require elemental analysis
