General description
Ammonium sulfide solution (aqueous ammonium sulfide) is a 20% solution in water. Ammonium sulfide is an inorganic salt with a sulfurous odor, which is commonly used in the food industry as a flavoring agent.[1] The influence of ammonium sulfide treatment on (100)GaAs (gallium arsenide) surfaces has been studied by X-ray photoelectron spectroscopy (XPS) and reflection high-energy electron diffraction (RHEED).[2] Its potential as an alternative to hydrogen sulfide for the transformation of activated amides to thioamides by thiolysis has been investigated.[3] The reaction of ammonium sulfide with 3-hydroxy-2-butanone over a range of temperature has been reported to form various flavor compounds.[4]
Application
Ammonium sulfide solution may be used to enhance the performance of type-II InAs/GaSb super lattice photodiodes by surface passivation technique.[5]

In the present work, Fe(3)O(4)-carbon nanotubes (CNTs) composite was explored as a sensing material candidate for ammonium sulfide. Intense chemiluminescence emission can be observed during the catalytic oxidation of ammonium sulfide on the surface of Fe(3)O(4)-CNTs composite. Based on this
