Phản ứng của Ozone trong nước Do cấu hình điện tử của nó, ozone có phản ứng khác nhau trong nước. Những chia làm ba loại: phản ứng oxy hóa-giảm phản ứng cycloaddition Electrophilic lưỡng cực thay thế các phản ứng Một cách thứ tư có thể phản ứng có thể được một số loại Ngoài ra ái nhân, mặc dù nó đã được kiểm tra trong nonaqueous Trong một số trường hợp, các gốc tự do được hình thành từ những phản ứng này. Những gốc tự do tuyên truyền thông qua các cơ chế của các bước cơ bản. | 2 Reactions of Ozone in Water Due to its electronic configuration ozone has different reactions in water. These fall into three categories Oxidation-reduction reactions Dipolar cycloaddition reactions Electrophilic substitution reactions A possible fourth way of reaction could be some sort of nucleophilic addition although it has only been checked in nonaqueous In some cases free radicals are formed from these reactions. These free radicals propagate themselves through mechanisms of elementary steps to yield hydroxyl radicals. These hydroxyl radicals are extremely reactive with any organic and some inorganic matter present in For this reason ozone reactions in water can be classified as direct and indirect reactions. The direct reactions are the true ozone reactions that is the reactions the molecule of ozone undergoes with any other type of chemical species molecular products free radicals etc. . The indirect reactions are those between the hydroxyl radical formed from the decomposition of ozone or from other direct reactions of ozone with compounds present in water. It can be said that direct ozone reactions are the initiation step leading to indirect reactions. OXIDATION-REDUCTION REACTIONS Redox reactions are characterized through the transfer of electrons from one species reductor to another one oxidant .3 The oxidizing or reducing character of any chemical species is given by the standard redox potential. Ozone presents one of the highest standards of redox potentials 4 only lower to those of the fluorine atom oxygen atom and hydroxyl radical see Table . Because of its high standard redox potential the ozone molecule presents a high capacity to react with numerous compounds by means of this reaction type. This reactivity is particularly important in the case of some inorganic species such as Fe2 or r. However in most of these reactions there is no explicit transfer of electron but rather an oxygen transfer from the ozone molecule to
