摘　　要：研究了用ICP-AES法同时测定高纯铯盐中Mn、Mg、Sr、Ca、Ba的方法。在选定的仪器工作参数下，加标回收率达到96％～104％，对合成样品10次重复测定的相对标准偏差〈0．5％，方法简便快捷。A method for the simultaneous determination of Mn, Mg, Sr, Ca, Ba elements in high pure CsI was studied. Under the selective parameters of instrument, the recoveries of standard additions are between 96% and 104%. The RSD of ten times repeated determination for the sample is less than 0.5 %. The method is simple. The results are satisfactory.
