摘　　要：用Ｎ２ＯＣ２Ｈ２原子吸收法来测定某型导弹热电池耐碱棉纸中的铁含量。并对测定条件和干扰困素进行了综合考虑。该测定方法具有很好的灵敏度，很好的精确度、干扰少、选择性和重现性好等优点。相对标准偏差ＲＳＤ＜１．０％（ｎ＝１０）。标准加入回收率均在９８％～１０２％（ｎ＝３）范围内。完全适用于耐碱棉纸中的含铁量的控制和样品系统分析。在实际应用中取得了很好的效果。Iron content in alkali resisting cotton paper of some type of missile's thermal battery is measured by N 2O C 2H 2 atomic absorption process synthetically considering measuring conditions and factors.The method possesses many advantages such as high sensitivity and accuracy,less interference and good repeatability and selectivity.The deviation RSD<1.0%( n =10) comparing to standard value.The standard adding recovery is in the range of 98%～102%( n =3).The use of the method,fully suited to the control of Iron content in alkali resisting cotton paper and the analysis for sample system,has obtained good effect in practice.
