Research on the Detection of Acetone Gas Using 4-Nitrobenzene Hydrazine Films

本文利用4-硝基苯肼制备出以玻璃片为基底的气敏薄膜，通过对吸收光谱以及拉曼光谱的分析对气敏薄膜对丙酮气体的气敏特性进行验证与分析，并对其反应机理进行分析，并且所制备的气敏薄膜与丙酮气体反应前后在空气环境中均具有良好的稳定性。本文最终对丙酮气体检测提出了一种新方法。In this paper, 4-nitrophenylhydrazine was used to prepare a gas-sensitive film based on glass sheets, and the gas-sensitive characteristics of the gas-sensitive film to acetone gas were verified and analyzed by the analysis of absorption spectroscopy and Raman spectroscopy, and its reaction mechanism was analyzed, and the prepared gas-sensitive film had good stability in the air environment before and after the reaction with acetone gas. Finally, a new method for acetone gas detection is proposed.
