摘要
对溴苯水溶液进行了电子脉冲辐解瞬态吸收光谱的研究 ,分别考察了体系中出现的OH自由基、H原子和水合电子e- aq等活性粒子与溶质的反应 .对瞬态吸收光谱中的主要吸收峰作了归属 ,表明中间产物为OH加合物、H加合物、苯自由基等 .初步研究了这些瞬态物种的生长、衰减行为 。
The reaction mechanism of bromo-benzene with OH, H and e+- aq in aqueous solution was studied by transient technology. It was showed that active particles from pulse radiolysis of aqueous solutions reacted with bromo-benzene. The main absorption peaks in these spectra were attributed to OH-adduct, H-adduct and C 6H 5 as the intermediate products. The build-up and decay of the transient species were studied. The reaction mechanism in the system was explained.
