【摘要】 在本文中,作者对ClO2进行了一些新的思考,首次明确地提出了ClO2在水溶液中有使水非.离.子.化.水解反应的新概念,导致了有比ClO2本身更强氧化能力的以羟基自由基HO·为主的多种活性氧化物种产生,从而可较好的解释原来很多仅用ClO2不能解释的问题。由于HO·的强氧化性和在催化剂存在下非离子化水解产生的HO·浓度会大大增加,可以很好解释二氧化氯水溶液对细菌有很强的杀菌能力、对难解除的有机化合物有强的氧化降解能力。因此,我们认为应该将二氧化氯催化技术视作一种高级氧化技术。
【Abstract】 In this paper, some new thinkings to chlorine dioxide are presented, it is first clearly pointed out that in ClO2 aqueous solution there is a non-ionization hydrolysis reaction, as follows. ClO2+H2O—→HClO2+·OH In light irradiation or on heating, there are also the following reactions:ClO2—→·O+ClO·;·O+H2O—→2·OH; 3·O—→O3; O3+H2O—→2·OH+O2.Due to ·OH (Free radical of hydroxyl, E°=2.80V), original or subordinate, existence, ClO2 aqueous solution has very great oxidisability, and therefore the big killing capability to microbe and the strong degradability to organic compounds of ClO2 aqueous solution can be explained very well. Thus, We should think of the catalytic oxidation of chlorine dioxide. as an advanced oxidation technology.
