摘　　要：提出用石油醚溶解样品 ,硝酸 (1 +99)萃取 ,火焰原子吸收法测定叠氮树脂中痕量铜和铁的方法。铜、铁的相对标准偏差均小于 4.5% ,回收率在 97.0 %～ 1 0 2 .0 %之间 。A method for determining copper and iron in azide resin is presented. The sample is dissolved with petroleum ether and copper and iron are stripped with HNO 3 (1+99), and then they are determined by the flame atomic absorption spectrophotometry. The method is convenient, sensitive and rapid. The RSD of both elements are less than 4.5%, and their recoveries are between 97.0%~102.0%.
