Objective. Describe the method of determining mass concentrations of ozone in the air of rooms of different air volumes during household ozonation.
Materials and methods. In the study, a multifunctional household ozonator was used to generate ozone, which was placed in an experimental chamber with a volume of 0.096 m3. The ozonator was set to maintain a target concentration of 0.1 mg/m3 and a productivity of 10 g/60 min. according to the passport. The analysis of air samples was carried out after different times of ozonation based on the requirements of the passport for the use of the device for 30, 60 and 180 minutes.
Selection and analysis of air samples was carried out using a Horiba APOA-370 ozone gas analyzer. The principle of operation of the analyzer is the method of non-dispersive ultraviolet absorption with cross-modulation (NDUV).
Statistical analysis of measurement results was carried out using descriptive statistics using the STATISTICA program.
Results. The mass concentrations of ozone, which were measured under conditions of air saturation of the experimental chamber of 0.17 g/0.096 m3 in one minute, were further used to calculate the possible concentrations of ozone in the room air.
The following formulas were proposed to calculate the concentration of ozone in the room air during ozonation): C1 = C2 x k, where C1 is the estimated concentration of ozone that can be formed during ozonation (mg/m3); C2 the concentration of ozone in the chamber, which is formed during the operation of the ozonator with the specified productivity of the device (mg/m3); k is the calculated ratio of the air volumes of the experimental chamber and the room.
The air volume in this case is 12.5 m3, and the calculated coefficient is 0.00768. Depending on the change in the air volume of the room, the coefficient may change, which in the future makes it possible to use this approach to calculate the concentration of ozone in rooms with different air volumes.
Conclusions. It is shown that this approach can be used when installing ozonators in rooms with different air volumes. Violation of the rules for using the ozonator and exceeding the ozone content in the room can cause poisoning, which is manifested by the following symptoms: headache, dizziness, severe fatigue, reduced work capacity, breathing disorders, irritation of the upper respiratory tract, allergic reactions, burning and reddening of the eyes, etc.
