General description

Ammonium hydroxide is a weak base mainly used as a source to prepare other ammonium compounds like urea, ammonium carbonate and ammonium sulfate etc.
Ammonium hydroxide solution is a solution of 30-33% NH3 in H2O. It is a colorless liquid having a strong characteristic odor. Electrolytic deposition of silver onto vitreous carbon electrodes from ammonium hydroxide solutions by the potential step technique has been reported.

Application

Ammonium hydroxide solution may be used:
  • As a medium to prepare magnetite (Fe3O4) nanoparticles via a modified controlled chemical coprecipitation method.
  • As a solvent and reagent to prepare 4-aryl and 4-alkyl-2,6-dimethyl-1,4-dihydro-3,5-pyridinedicarboxylates via Hantzsch synthesis in a microwave cavity synthesizer.
Ammonium hydroxide solution may be used in the following studies:
  • Preparation of magnetic nanoparticles.
  • To investigate the effect of substrate on the morphology of ZnS thin films by chemical bath deposition.
  • Preparation of amine functionalized cellulose nanocrystals (CNC-NH2).
  • Wet processing of the GaAs(100) surface.
