摘要
Abstract
A novel method for determination of the nitrogen content in nitrocellulose was established using a polarized light microscope. Senarmont method was used to determine the average optical path difference. The results show that the relationship(w= -0. 046 6λ+ 12. 388) between the nitrogen content and the optical path difference was linear with a correlation coefficient of 0. 999 3 when the range of the nitrogen content in nitrocellulose were 11.0％-13.8％. Certified nitrocellulose reference materials were used to evaluate the method and the results show that the recoveries ranged from 99.7 ％ to 100.2 ％ with the relative standard deviations falling between 0.15％ and 0.20％. The method is simple , accurate and environment-friendly.关键词
