  • 摘要: 利用瞬态吸收光谱技术进行了不同条件下4-氯酚水溶液的电子脉冲辐解,分别研究了体系中瞬时出现的·OH,H和水合电子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做了归属,得到了OH-adduct,H-adduct和氯代酚氧基等一系列中间产物,并初步研究了这些瞬态物种的生长、衰减行为和可能的反应机理,得出了一些微观反应的速率常数。
    Abstract: The pulse radiolysis of 4-chlorophenol in different water solutions was studied with transient ab-sorption spectrum. In this system, active particles such as·OH radical, hydrated electron and H atom that result from radiolysis of water can react with the solute. We studied the main absorption peaks in these spectra and found the main intermediate products such as OH-adduct, H-adduct and chlorinated phenoxyl radical. The build-up and decay of the transient species as well as the reaction mechanism were also studied. Several reaction rate constants were calculated.
