摘要
用Ｘ射线衍射方法，研究了Ｃａ２＋、Ｓｒ２＋和Ｂａ２＋离子交换１３Ｘ分子筛的结构。证明离子交换后的分子筛基本结构未变，仍为立方形；但晶胞常数，衍射峰的数目和强度却发生了变化。文章讨论了衍射谱结构与吸附性能之间的关系。
Using X-ray diffraction, the structures of 13X molecular sieve are studied by changing Ca2+, Sr2+ and Ba2+ ions exchange method. After canons exchanging, the molecular sieves structures do not change, which keep cubic. But cell constant, diffraction site and intensities have been changed. The relations between diffraction spectra and adsorption properties are discussed.
