Abstract

Examination of the cation-exchange capacity of a hydrated halloysite from Djebel Debar has disclosed no evidence for the proposed existence of exchangeable interlayer ions. A series of labile halloysite-salt complexes has been prepared. The requirements for effective intercalation of the salt are a high salt concentration in the external solution phase and a cation of low hydration energy.

During the course of this work, a brief account of which has been given previously (Garrett and Walker, 1957), tile penetration of ammonium fluoride into the interlayer regions of the Djebel Debar halloysite was reported by Weiss, Mehler, Koch and Hofmann (1956). More recently, Wada (1959) has described the intercalation of a number of salts in a halloysite from Japan.
