Abstract

Kinetic study for the heterogeneous decomposition of hydrogen peroxide over different non-soluble metal oxides (CuO, Fe₂O₃ and PbO₂) was taken as a model reaction, mainly in normal micellar, inverse micellar microemulsion of sodium dodecyl sulfate (SDS). Other micellar phases of different surfactants [sodium dioctylsulfosuccinate (AOT), cetyle trimethyl ammonium bromide (CTAB) and triton X100] have been studied. Different organic solvents have been investigated. A promotional effect was generally observed. The reaction rate determining step was estimated. Reaction rate constants and thermodynamic parameters (ΔG^*, ΔH^* and ΔS^*) were calculated. It was found that the highest promotional influence was observed in the case of (SDS/Fe₃O₄) in micellar and inverse micellar micro-emulsion media.

Kurzfassung

Die Untersuchung der Kinetik des heterogenen Zerfalls von Wasserstoffperoxid über verschiedene nichtlösliche Metalloxide (CuO, Fe₂O₃ and PbO₂) wurde hauptsächlich in normalen mizellaren und inversmizellaren Mikroemulsionen von Natriumdodecylsulfat (SDS) als Modellreaktion genommen. Andere mizellaren Phasen von verschiedenen Tensiden [Natriumdioctylsulfosuccinat (AOT), Cetyl-trimethylammoniumbromid (CTAB) und Triton X100] sind in verschiedenen organischen Lösungsmitteln untersucht worden. Allgemein wurde ein fördernder Effekt beobachtet. Die Geschwindigkeit des reaktionsbestimmenden Schrittes wurde abgeschätzt und die Reaktionsgeschwindigkeitskonstante sowie die thermodynamischen Parameter (ΔG^*, ΔH^* and ΔS^*) berechnet. Der höchste fördernde Einfluss wurde im Fall von (SDS/Fe₃O₄) in mizellarem und inversmizellarem Mikroemulsionsmedium gefunden.
