低压条件下气态UF6纯度的红外光谱分析方法

FTIR Analysis Method for Purity Analysis of Gaseous UF6 at Low Pressure

  • 摘要: 为建立低压条件下使用傅立叶红外光谱法定量分析气态UF6的纯度方法,本研究选取1 150 cm-1处的吸收峰作为定量分析UF6纯度时的特征吸收峰。针对UF6气体净化后尾料中UF6残留量的在线分析需求,建立满足真空密封要求的红外分析系统、标准样品配比系统和背景图谱标定装置,对不同纯度、不同压力条件下的气态UF6标准样品进行分析,建立UF6纯度与其特征吸收峰面积、稳定压力相关的计算公式。结果表明,通过该方法可准确地得到60~140 Pa的压力范围内和0~100%的纯度范围内气态UF6的纯度。建立的分析方法和计算公式满足低压条件下UF6气体在线快速分析的要求。
    Abstract: In order to establish a method for quantitative analysis of the purity of gaseous Uranium hexafluoride using Fourier infrared spectroscopy under low pressure, the absorption peak at 1 150 cm-1 was selected as the characteristic absorption peak for quantitative analysis of the purity of uranium hexafluoride. It was showed that the pressure of gas analysis has a direct effect on the area of characteristic peak under low pressure condition, which could not be ignored in the process of purity calculation. Aiming at the online analysis demand of the residual UF6 in the tail material after UF6 gas was purified, the gas standard UF6 samples with different purity and pressure conditions were analyzed by establishing an infrared analysis system, a standard sample ratio system and a background spectrum calibration device that could meet the requirements of vacuum sealing. The calculation formula for the relationship between the UF6 purity and its characteristic absorption peak area as well as the gas absolute pressure were established. The experimental results showed that the purity of gaseous UF6 which was in the pressure range of 60~140 Pa and the purity range of 0~100% could be accurately analyzed by this method.
