摘要
对OH·自由基的先进氧化特性进行了研究,并对羟基的化学反应进行了分析.羟基形成时间极短,小于10-12s.OH·一旦形成,会诱发一系列的自由基链反应,氧化分解所有的有机物质、生物体,最终将其降解为CO2、H2O和微量无机盐,不存在有害有毒的残留物.羟基自由基参与的化学反应属于游离基反应,化学反应速度极快.化学反应时间小于1s,生化反应时间1~10s.
Hydroxyl radical generation is the mark of technology of advanced oxidation. This paper studied on the characteristics of advanced oxidation,analyzed chemical reaction of hydroxyl. The time of hydroxyl radical formation is very short, less than 10^(-12)s. Once it comes into being, hydroxyl will induce a series of radical chain reaction, oxygenolysis all the matter organic and organism, and its ultimate production is CO_2, H_2O and a little inorganic salt without harmful poisonous residues. The chemical reaction of hydroxyl radical is free radical reaction, whose reaction speed is very high. Its chemical reaction time is less than 1s, and biochemical reaction time is 1~10 s.
