摘要
用原子吸收法测定４ ，４′ 二氨基二苯醚中钠和钾，分析了干扰因素，得出了测定条件，为纯化聚酰亚胺的原料提供了检测手段．
The quantity of sodium and potassium in 4,4'?diamino?diphenyl oxide were measured by atomic absorption spectrophotometry.The influence factors were analyzed and the measurement conditions were obtained.For the purity of material of the high pure polyimide,a fine analytical method was presented.
