| Abstract: | 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%. |
