일반 설명
Sulfamic acid (H2NSO3H) is widely used inorganic compound. It exists in zwitterionic form and neutral forms. Zwitterionic form has been reported to be is more stable than neutral form. Its industrial applications have been reported. It has various organic synthesis applications.
Sulfamic acid is a strong inorganic acid. It is a hypochlorite scavenger. The ability of sulfamic acid to reduce nitrate to nitrogen gas under acidic condition has been utilized to denitrify nitrate-rich wastewater along with zinc powder.
