摘　　要：建立了一种新的分析法分析火药中硝化棉的含氮量。火药试样预处理后，可利用 NC2000氮元素分析仪直接进行氮的测定。相对标准差＜1.89%，回收率为98.52%～100.34%，结果满意。该法简单、快速、精密度和准确度高、无毒、安全。After the pretreatment of the powder sample, nitrocotton in the sample was separated and purified. Then the content of nitrogen in the nitrocotton was determined by the NC2000 nitrogen analyzer. The precision and recovery tests were performed by using six standard samples. The results show that,RSD is less than 1.89%, and recovery is in the range of 98.52% to 100.34%. The method is simple, rapid and safe in operation, has high precision and accuracy.
