Description

technical field [0001] The invention relates to an ozone decomposition experiment device, which is used for ozone decomposition experiments in the fields of environmental science, environmental chemistry, environmental material science, environmental engineering and the like. Background technique [0002] Ozone is also known as triatomic oxygen, commonly known as "Fu oxygen, super oxygen, active oxygen", and its molecular formula is O 3 . Ozone is a light blue gas at normal temperature and pressure. It has extremely poor stability and can be decomposed into oxygen at room temperature. Therefore, ozone cannot be stored. It is generally produced on site and used immediately. Ozone is currently known as a broad-spectrum, efficient, fast, safe, and non-secondary pollution sterilizing gas, which can kill bacterial spores, viruses, fungi, etc., and can destroy botulinum toxin, so it is widely used in various Water quality treatment, medical sanitation, food preservation and remo...
