为了研究硝化纤维的荧光光谱和定量方法, 利用紫外激发荧光技术, 首先对硝化纤维丙酮溶液进行了荧光分析, 通过三维扫描得到了硝化纤维的紫外激发荧光光谱, 确定了最大荧光相对强度时激发波长为 355.0 nm、发射波长为 354.5 nm; 然后在发射波长 354.5 nm条件下, 测定了不同浓度的硝化纤维丙酮溶液荧光相对强度, 对试验结果进行了线性回归, 确定了硝化纤维的定量方法。

The technology of fluorescence excited by ultraviolet is used for the study of fluorescence spec. trum and quantitative methods of nitrocellulose. Firstly, fluorescence analysis process is implemented on the nitro. cellulose in the solution of acetone. The fluorescence spectrum of nitrocellulose excited by ultraviolet is obtained through three-dimensional scanning technology. So the wavelength of excitation and emission are 355.0 nm and 354.5 nm respectively at the maximum fluorescence relative intensity. Then the fluorescence relative intensities of nitrocellulose in acetone with different concentrations are measured under the condition of 354.5 nm emission wavelength. So the quantitative method of nitrocellulose is determined through the linear regress of the experi. ment result.
