The June 2023 edition of the International Journal of Engineering and Advanced Research in Technology (IJOEAR) publishes an article titled “Stoichiometry and Kinetics of Hydroxyl Radicals in Air Quality,” authored by Garcia Raurich, Josep; Torres Lerma, Jose Antonio; Monagas Asensio, Pedro; Martinez Vimbert, Roberto; Arano Loyo, Mariona; Martinez Roldan, Tania.
The article demonstrates how the PUROH technology perfectly imitates nature in the process of environmental sanitization for indoor spaces, based on the Open Air Factor (OAF). One of the most interesting conclusions is that using only two reactive elements: hydrogen peroxide and negligible amounts of ozone, the same levels of hydroxyl radicals are achieved as those used by nature to decontaminate and sanitize the air.
In more detail, the paper discusses the stoichiometry1 and kinetics of the hydroxyl radicals emitted by this technological device based on the Open Air Factor (OAF), designed to control indoor air quality. The study analyzes the decomposition of the number of hydroxyl radical molecules (OH·) when reacting in the presence of typical atmospheric pollutants such as CO2, hydrocarbons, and bicarbonate ions.
The environmental health that nature provides us daily is linked to the sanitization produced by atmospheric chemistry through oxidative processes that occur under the powerful sunlight penetrating the clouds and reaching forests, oceans, and seas, where multiple reactions, recombinations, mineralizations, degradations, etc., take place. This chain reaction is called the Open Air Factor (OAF), which cleans and disinfects the environment in which all living beings, known as the biosphere, reside.
Precisely in this process of environmental sanitization for indoor spaces, replicating the natural detergent of the Open Air Factor (OAF), it is necessary, for the sake of safety and efficiency, to analyze the quantitative proportions or mass relationships of the chemical elements involved and participating in this natural chemical reaction. It is also important to study the proportion of the resulting elements and the composition of the chemical mixtures of the components.
Comparing the stoichiometry provided by nature with similar artificial systems for indoor spaces will give us insight into how similar the processes and results are.
The article analyzes the decomposition of the number of hydroxyl radical molecules (OH·) when they react with typical atmospheric pollutants such as CO2, hydrocarbons, and bicarbonate ions. Unlike the multiple reactants that exist in nature, these quantities of hydroxyl radical molecules (OH·) are generated with only two reactants, hydrogen peroxide and ozone, following current international safety regulations regarding their emissions in the presence of people.
1Stoichiometry is a branch of chemistry that deals with the quantitative relationships between reactants and products in a chemical reaction. In other words, it studies the proportions in which chemical elements combine and how the quantities of reactants and products in a given chemical reaction can be predicted.
