ICP-AES测定Beta沸石分子筛中的Si和Al

Determination of Si and Al in Beta Zeolite by ICP-AES

研究了 Beta沸石分子筛中 Si、Al元素的 ICP- AES分析方法 ,考察了溶液中酸度、高频功率、积分时间对测定的影响 ,以及共存元素间的相互干扰及干扰的校正方法。优化了工作条件 ,方法的相对标准偏差均小于 5 % ,回收率为 98%— 10 5 %。

A method for determination of Si and Al in beta zeolite by CID and ICP-AES was established,under the optimized experimental conditions,the interference of coexistent elements was prevented.The accuracy, precision and the recovery (98%-105%) of the method are satisfactory.
