The method of simultaneous determination of main content elements (Si and Al) and impurity elements (Fe ,Na ,Ca and Mg)in zeolites and supports has been studied by using ICP AES technique. The samples were pretreated by microwave digestion.

• 本文研究了用微波消化试样，ICP－AES法同时测定分子筛及担体中的主含量元素Si、Al和杂质元素Fe、Na、Ca、Mg的方法。
