利用自行研制的微秒级脉冲辐解实验装置,在KBr,KI 和KCNS水溶液的脉冲辐解中观察到了Br_2~-·I_2~-·和(CNS)_2~-阴离子自由基的瞬态吸收光谱。这些阴离子自由基的形成都和水辐解的初级产物OH自由基有密切联系。本文简要介绍了脉冲辐解实验装置,对上述三种阴离子自由基的形成及衰减动力学进行了简单讨论。
The transient absorption spectra of Br_2 ~ - I_2 ~ - · and (CNS) _2 ~ - anions were observed in the pulsed radiolysis of KBr, KI and KCNS aqueous solutions . The formation of these anionic free radicals are closely linked to OH radicals, the primary products of water-liberation. In this paper, a brief introduction of pulsed radiolysis experimental apparatus is given, and the formation and decay kinetics of the above three anionic radicals are discussed briefly.
