Abstract

The adsorption-catalyzed degradation of parathion on clay surfaces is a hydrolysis process, proceeding either directly or through a rearrangement step. The rate and mechanism of degradation are dependent on the nature of the clay, its hydration status, and saturating cation. A mechanism for parathion degradation at adsorption sites on clay surfaces, in the absence of a liquid phase, is proposed.

Резюме

Резюме

Адсорбционно-каталитическая деградация паратиона на поверхностях глины является гидролизным процессом, протекающим непосредственно или через стадию перегруппировки. Скорость и механизм деградации зависят от природы глины, ее состояния гидратации и насыщающего катиона. Предлагается механизм деградации паратиона в местах адсорбции на поверхностях глины, в отсутствии жидкой фазы.

Kurzreferat

Kurzreferat

Die durch Adsorption katalysierte Degradation von Paration, welches sich auf Tonoberflächen befindet, ist ein Hydrolysenprozeß, der entweder direkt oder durch eine Umlagerungsstufe vor sich geht.Die Geschwindigkeit und der Mechanismus der Degradation hängt von der Natur des Tones und der Kationen und des Tones Hydrationszustand ab.Ein Mechanismus für die Parathiondegradation an den Adsorptionsplätzen auf Tonoberflächen, in Abwesenheit einer flüssigen Phase, wird vorgeschlagen.

Résumé

Résumé

La dégradation catalysée par adsorption de parathion sur des surfaces argileuses est un processus d'hydrolyse. découlant soit directement, soit d'une étape de réarrangement.La vitesse et le méchanisme de dégradation dépendent de la nature de l'argile,de son statut d'hydratation,et de son cation de saturation. Un mécanisme est proposé pour la dégradation de parathion à des sites d'adsorption sur des surfaces argileuses, sans phase liquide.
