Determination of Organic Compounds by Atomic Absorption Spectrophotometry (AAS) with Special Reference to Compounds Encountered in Environmental Problems
… has been devised utilising the fact that "ferroin" is strongly adsorbed on silica gel. The procedure is based on the quantitative formation of the ion-association complex (Fe phen3)2+, (saccharin)2, when an acetone (70%) or methanolic (86%) or ethanolic (60%) solutions of saccharin is …

Anomalous Wave Dispersion in the Cyclohexanedione-Bromate Chemical Oscillator
… portion of the behavior observed in the Ferroin-catalyzed cyclohexanedione variant of the Belousov-Zhabotinsky (CHD-BZ) reaction. The phenomena of anomalous velocity dispersion (in which following waves may catch up to, rather than fall behind an initial excitation wave), wave-stacking, …

Prinzipien der Selbstorganisation: Untersuchungen zu Strukturbildenden Prozessen und Entwicklung einer experimentellen Konzeption zur Einbindung dieser Thematik in einen zeitgemäßen Chemieunterricht
… Gas-Flüssigkeit. Des Weiteren ist ein Ferroin-katalysierter Ansatz der BZ-Reaktion gefunden worden, bei dem durch potentiometrische Verfolgung im ungerührten Zustand eine schulische Demonstration determiniert-chaotischer Verhaltensweisen möglich ist. Ein weiterer Aspekt der Arbeit …
