General description
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
Application
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
