摘要
利用激光光解技术对废水中苯酚的降解机理进行了详细研究．结果表明苯酚中性水溶液在２４８ｎｍ激光的作用下，苯酚分子立即发生电离，生成阳离子自由基，然后再脱氢生成较稳定的中性自由基，并对苯酚在酸、碱、二氯化锰淬灭剂、氧化剂作用下的行为进行了比较，并测定了有关动力学数值．
Phenol is very light (UV) sensitive, and can be readily photo - ionized to produce some transient species, such as radical cation, neutral species. The laser flash photolysis of phenol has ben performed for the first time. The mechanism of photo - ionization has been confirmed and illustrated. In addition, the related reaction rate constants and molar extinction coefficients of the transient species have been determined. This can give some advice to degradate organic waste water with phenol.
