Descrizione generale

Ammonium hydroxide is a weak base with an increasing dissociation upon dilution. The base serves as a;
  • precipitant for the R2O3 group of elements,
  • complexing agent,
  • dissolution medium.7

Applicazioni

Ammonium hydroxide may be used;
  • to clean wafers.1
  • to prepare magnetic iron oxide nanoparticles
  • in the recovery of cellulose from sugarcane bagasse. The process enhances hydrolysis and -production of bioethanol
  • in bi-directional perfusion technique of human periodontal ligament cell sheets
  • as a mobile phase in the liquid chromatography for prebiotic galactooligosaccharides
