Figure 6: The layer model for aluminized vermiculite structure and implications for Cs+ mobility.

From: Crystal structure control of aluminized clay minerals on the mobility of caesium in contaminated soil environments

Figure 6

(a) Aluminized vermiculite is composed of an interstratification of unaltered Na+-saturated vermiculite layers and hydroxy-interlayered layers containing both Al(OH)x3−x islands and Na+ cations. (b,c) For unaltered vermiculite layers, Cs+ cations are immobilized by the collapse of the structure whereas Cs+ remains mobile in the hydroxy-interlayered layers and exchangeable with NH4+ ions.
