摘　　要：利用纳秒级脉冲辐解技术对喹啉在多种条件下降解过程中所生成的瞬态粒子行为进行了详细分析。探讨了喹啉在羟基、氢自由基、水合电子、SO4.-,Br2.-、叠氮化钠等作用下生成的瞬态粒子的吸收光谱、瞬态粒子的生成和衰减行为,可作为实际含喹啉废水溶液降解研究的理论参考。Quinoline＇s degradation was studied by pulse radiolysis. It was found that hydrated electron, hydrogen radical, hydroxyl radical and SO4^· - can react with quinoline. The absorption spectra of the transient species of quinoline were obtained, and related constants were determined, but it was found that the species of Br2^·- and N3^·- can＇ t react with quinoline. The results give us some advices for studing the degradation of quinoline.
