Description

Other Notes

For 294993-230G-EU packaging: 500 mL of aluminium cylinder equipped with stainless steel valve.

Packaging

170 g in steel cylinder

Application

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.

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.

Reagent for chemical vapor deposition of TiN.
