| 摘 要： | 介绍了一种新的产生单重态氧（O2（1△g）的气固化学反应体系，即在固定床式反应器中采用固体过氧化钠粉末与氯气（Na2O2/Cl2）进行反应的气固化学反应体系。实验分别通过用对近红外敏感的光谱仪和锗探头监测了反应产生的（O2（1△g）的发射光谱和1 270 nm的光信号，同时通过数据采集系统监测了反应池固体反应层和测试池中气体的温度的变化曲线。实验测得了（O2（1△g）在1 270 nm附近的特征发射光谱，此光谱表明该体系是一个很好的产生（O2（1△g）的体系，同时，实验现象表明该反应是强放热反应。

| Abstract: | A new gas-solid reaction system for singlet oxygen generation in which sodium peroxide reacted with gaseous chlorine(Na_2O_2/Cl_2) in a fixed-bed reactor was reported.The singlet oxygen emission spectra from Na_2O_2/Cl_2 reaction system were recorded by a near-IR sensitive Optical Multichannel Analyzer(OMA-V) and a visible sensitive CCD Optical Spectroscopy Analyzer(OPA).The 1 270 nm optical signal and the temperature of reaction zone and detection zone of the Na_2O_2/Cl_2 reaction systems were monitored by a Ge-detector and a data-collection system,respectively.The experimental results showed that singlet oxygen was produced in the Na_2O_2/Cl_2 reaction system,but the process was accompanied with a drastically strong heat release. |
