Abstract

High-pressure ion exchange of small-pore zeolite K-natrolite allows immobilization of nominally non-exchangeable aliovalent cations such as trivalent europium. A sample exchanged at 3.0(1) GPa and 250°C contains about 4.7 Eu III ions per unit cell, which is equivalent to over 90% of the K + cations being exchanged (see picture).
