The Fixation Phenomenon of Adsorbed Cations on Halloysite Caused by Drying

Abstract

In part I of this series physico-chemical studies on the fixation phenomenon of the cations adsorbed on kaolinite caused by drying were carried out and a new theory of the fixation of adsorbed cations, being quite different from any current theories which have been introduced so far by soil scientists, was advanced by the authors.In the present paper the fixation phenomenon of adsorbed cations such as Li+, Na+, K+ and Ca++ on halloysite surface caused by drying was studied. it was confirmed that the mechanism of the fixation for kaolinite may also be applicable to halloysite.
