Abstract

The literature on thermal analysis of ferrous sulphate heptahydrate in air is reviewed. The oxidation-decomposition of ferrous sulphate heptahydrate is a complex function of experimental conditions. Some general methods including those developed by the authors for the purpose of analyzing various intermediates encountered during the oxidation-decomposition of the heptahydrate are presented and discussed.

Résumé

On présente une mise au point bibliographique sur les publications concernant l'analyse thermique dans l'air du sulfate de fer(II) heptahydraté. La décomposition oxydante du sulfate de fer(II) heptahydraté est une fonction complexe des conditions expérimentales. On expose et discute quelques méthodes générales, y compris celles que les auteurs ont développées, afin d'analyser les différents états intermédiaires intervenant lors de la décomposition oxydante de l'heptahydrate.

Zusammenfassung

Eine Literaturübersicht über die Thermoanalyse der Eisen(II)sulfat Heptahydraté in Luft wird gegeben. Die oxidative Zersetzung des Eisen(II)sulfat Heptahydrats ist eine komplexe Funktion der Versuchsbedingungen. Einige allgemeine Methoden, einschließlich der von den Autoren zur Analyse verschiedener im Laufe der oxidativen Zersetzung des Heptahydrats entstehenden Zwischenverbindungen, werden beschrieben und erörtert.
