Going back to 1785, Martinus van Marum, a Dutch chemist was the first person to become in contact with Ozone while conducting experiments involving electrical sparkling above water.
He noticed a strange smell which he attributed to electrical reactions; little he knew that he had artificially created Ozone.
Some decades later, in 1840, Christian Friedrich Schonbein, a German Chemist succeeded in isolating the gaseous chemical and named it “Ozone”. Its formula, O3, was determined by Jacques Louis Soret in 1865 and confirmed by Schonbein in 1867. Since then, ozone uses, and applications are still evolving and growing and promise to be around for many years to come as scientist, engineers and manufacturers are in constant work to make this technology safe and accessible.
For more than a century, Ozone have been used for countless applications such as blood purification, therapeutic uses, treatment of water, food, waste, odor removal, air, virus, bacteria, mold, and the list goes on and on.
Definition
Ozone has been defined as a triatomic very reactive gas, composed of three oxygen atoms, is colorless or may have a pale bluish tone, and a pungent odor. It is considered a major air pollutant in the lower atmosphere but a beneficial component of the upper atmosphere because it protects the earth against harmful Ultraviolet radiation. It is used for oxidizing, bleaching, disinfecting, and deodorizing among other uses. Ozone can be found naturally or can be artificially generated.
Ozone gas is a powerful oxidant and because of this property, it can cause damage to mucous and respiratory tissues in humans and animals when exposed to high concentrations for long periods of time. It is also a very volatile gas, which allows it to degrade quickly transforming itself back into breathable oxygen. It is a very unstable gas and because of this, it is impossible to store or pack.
