On corrosion inhibitors II: Research on the additivity of K and A inhibitors on iron The influence of impurity ions on the protection characteristics of K inhibitors on ironAn explanation is given of the onium thesis and of the notion of the K and A inhibitors. Possible inter-effects of K and A inhibitors with the metal surface are discussed. The behaviour of K and A inhibitors in the combination test is at least additive, frequently super-additive. Dissolved impurity metal ions enhance the protective effect of the K inhibitors in the following order:\documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm Hg 〈 Ni 〈 Ag 〈 Pd 〈 Cu}{\rm .} $$\end{document}The protective effect is increased by lower concentrations of FeIII ions, and decreased by higher concentrations. The influence of FeII ions is small, and depends very little on the concentration.
Notes:
Die Oniumhypothese und der Begriff des „K- und A-Inhibitors“ werden erläutert. Mögliche Wechselwirkungen der K- und A-Inhibitoren mit der Metalloberfläche werden diskutiert. K- und A-Inhibitoren verhalten sich im Kombinationsversuch mindestens additiv, häufig überadditiv. Gelöste Fremdmetallionen erhöhen in der Reihenfolge:\documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm Hg 〈 Ni 〈 Ag 〈 Pd 〈 Cu}{\rm .} $$\end{document}Die Schutzwirkung der K-lnhibitoren. Geringe Konzentrationen an FeIII-lonen verstärken, höhere Konzentrationen erniedrigen die Schutzwirkung. Der Einfluß von FeII-lonen ist gering und wenig won der Konzentration abhängig.
