Abstract

Abstract Ion exchange behavior of analcime-leucite mineral was discussed in this work. Leucite was firstly prepared from analcime in 3.0 mol/L K2CO3 solution, and a liner relationship was fitted between temperature and ion exchange extent. Na+ and K+ distribution in analcime-leucite mineral and Na+-K+ mixed solutions were investigated by varying the K/(K + Na) molar ratio in solution from 0 to 1.0. It turned out that the mutual conversion between analcime and leucite can be realized depending on solution composition, but analcime had a wide stable range of K/(K + Na) ratio in the solutions, indicating Na+ was more accessible into the analcime-leucite framework. Present results also made it necessary to reevaluate the K+ extraction and harmful metal ion immobilization ability of analcime-leucite mineral under the influence of Na+.
