摘要
臭氧作为一种强氧化剂,可以用于水处理、环境消毒等很多方面,本研究的目的在于弄清其作用过程和反应机理,以便对其实际应用提供理论指导.目前,人们在这方面的研究有不同的结论.首先从理论上推导了臭氧在碳酸盐水溶液中的分解动力学方程,然后通过实验予以论证.研究表明,在碳酸盐体系中,臭氧的分解过程与溶液的pH和剩余臭氧浓度密切相关,其动力学方程为:-d[O3]/dt=kO3,OH-[OH-][O3].
As a strong oxidant,ozone can be used for water treatment,environmental sterilization and so on.It is important to make the action process and reaction mechanism clear.At present, people have different conclusions on this study.In this article,the decomposition dynamics equation of ozone in carbonate solution is deducted and proved through experiment. The study shows that in carbonate system,ozone′s decomposition process is directly related to the pH of solution and the concentration of the residual ozone. The decomposition dynamics equation is:-d/dt=k_(O_3,OH^-).
