The study of specific reactions of hydrogen radical under ambient conditions

为了研究氢自由基在环境条件下的反应特性，我们制作了一个氢自由基发生器，并对其性能进行了评价。氢自由基发生器由氢气反应池和波长为160 ~ 400nm （3.8 ~ 7.7 ev）的紫外块组成。用质谱联用常压电晕放电电离源证实了氟化氢的生成。质谱分析表明，这些峰对应于氢自由基与反应池聚四氟乙烯壁反应产生的负簇离子F-(HF)n。

To examine the reaction characteristics of hydrogen radicals under ambient conditions, we have made a generator of hydrogen radicals and estimated its performance. The hydrogen radical generator consists of a reaction cell of hydrogen gas and an ultraviolet lump of 160-400nm (3.8-7.7eV) in wavelength. The generation of hydrogen fluoride (HF) was confirmed with a mass spectrometer combined with an atmospheric pressure corona discharged ionization source. The mass spectrum showed the peaks corresponding to negative cluster ions F-(HF)n originating from the reactions of hydrogen radicals with Teflon wall of the reaction cell.
