Opis ogólny

Ammonium hydroxide solution is also called aqueous ammonia, aqua ammonia, or ammonia water. It is a weak base mainly used as a nitrogen source to prepare other nitrogen-containing organic and inorganic chemicals such as urea, ammonium carbonate, ammonium sulfate, etc.

Zastosowanie

Ammonium hydroxide solution (28% NH3 in H2O) can be used as:
  • A medium to prepare magnetite (Fe3O4) nanoparticles via a modified controlled chemical coprecipitation method using divalent or trivalent iron salts as iron precursors.      
  • A reagent in ammonolysis.      
  • A solvent to synthesize 1, 4 dihydropyridines via one-pot condensation of an aldehyde and alkyl acetoacetate.

In this work, new magnetic-plasmonic nanocomposites have been developed through the use of two complementary polyelectrolytes⁻polystyrene sulfonate (PSS) and poly(allylamine hydrochloride) (PAH). PSS, a negatively charged polyelectrolyte, was utilized as a stabiliser for magnetite nanoparticles, and PAH, a positively charged
