Nitric acid (HNO3), also known as aqua fortis and spirit of niter, is a highly corrosive strong mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water.

HISEA CHEM could provide the complete set of nitric acid engineering services covers every stage. We take the latest technique to produce the nitric acid by the dual pressurization process.

Nitric acid in nature is mainly formed by nitric oxide generated in thunderstorm days or nitrogen dioxide released from microbial life activities. Human activities also produce nitrogen oxides. There are many nitrogen oxides discharged from human pollution sources every year in the world,
