防冰添加剂水溶液的紫外可见吸收光谱分析研究

Analysis of Fuel System Icing Inhibitors Water Solution with UV-Vis Absorption Spectrum

防冰添加剂的含量是航空喷气燃料检测的一个重要指标。防冰添加剂在水中良好的溶解度,目前常用测量其含量的方法,是将防冰添加剂萃取水溶液中,检测水溶液中防冰添加剂的含量。本文采用了紫外可见光谱分析方法测定了防冰添加剂水溶液的含量,分别对两种含量高低不同的标准液进行了测量,呈良好线性关系;同时又比较两者吸收峰的不同,并作了初步的解释。

The content of Fuel System Icing Inhibitors（FSII） is an important index for the detection of aviation jet fuel.The FSII has a good solubility in water,and the method of measuring the content of FSII is used to extract the content of FSII in the water solution.The paper made use of the determination of FSII water solution in ultraviolet visible spectrum and measured two kinds of high and low content of different standard solution.Both of two curves showed a good linear relationship.And at the same time the paper compared the two absorption peaks and made a preliminary explanation.
