Über die Kinetik der Reaktion zwischen Hydroxylamin und Salpetriger Säure

Abstract

Die Kinetik der Reaktion zwischen Hydroxylamin und Salpetriger Säure wird bei 25°C in acetatgepufferter (μ = 1,0) und nitritgepufferter (μ = 0,2) Lösung untersucht. In acetatgepufferter Lösung wird das Zeitgesetz in nitrigepufferter Lösung das Zeitgesetz gefunden. Die erhaltenen Ergebnisse werden vom Standpunkt der Chemie der Nitrosierung diskutiert.

Hydroxylamine electrochemistry at polycrystalline platinum in acidic media: a voltammetric, DEMS and FTIR study

“…0.5 and 1.0 V, probably has multiple sources. The most important source of N 2 O is a homogeneous reaction between HNO 2 and HAM [37], since a dramatic increase in N 2 O formation is observed at potentials where NO is oxidized to HNO 2 .…”

The Oxidation of Hydroxylamine on Gold Electrodes in Mildly Acidic Aqueous Electrolytes: Electrochemical and In Situ Differential Reflectance Studies

“…7 Although the activity of Hm for nitrite reduction either in the form of electropolymerized Hm films or layers of monomers mixed with didodecyldimethylammonium bromide ͑DDAB͒ has been well documented, 8 the present study appears to be the first involving a simple Hm monolayer spontaneously adsorbed on a carbonaceous surface for studies of this specific reaction. As will be shown, Hm|GC is inactive toward reduction of both HAM and nitrate 6 and, therefore, affords a highly specific means for monitoring solution phase nitrite without interference from those species. For these experiments, the Hm|GC disk electrode was polarized at a potential negative enough for nitrite reduction to ensue and placed directly in front of a Au disk electrode of much smaller area ͑A = 0.02 cm 2 , Bioanalytical System, West Lafayette, IN͒ as shown in Scheme 1.…”

The Oxidation of Hydroxylamine by Technetium(VII) in Hydrochloric Acid

“…The kinetics of (1) have also been studied in acetate and nitrate media [11] and found to be more complex than in HCIO4. In nitrate media the rate obeys Eq.…”

“…The kinetics and mechanism of the reduction of Pu and Np by NHjOH are well known [5,[8][9] and the reactions between HNO, and HNO2 and NH2OH have also been studied in detail [4,[10][11][12][13][14][15][16][17][18][19][20][21][22][23] and these results are summarized very briefly below. However, there is very little published Information about the reactions of NH2OH and technetium which is a potentially important reaction if NH2OH is to be used in U/Pu Separation.…”
