General description
This product aligns with one or more of the 12 Principles of Green Chemistry Find details here.
Application
Anhydrous ammonia has been used in dynamic reaction cell technology (DRC) to remove interfering ions without the loss of sensitivity. It has also been used for adjusting pH during the synthesis of magnetite-hematite mixture by combustion methods.
Ammonia may be used as a base to adjust pH for preparing mixed magnetite-hematite nanoparticles via combustion method. These nanoparticles show promising potential as sorbents for removing heavy metal ions from water.
Reagent for chemical vapor deposition of TiN.
