Abstract

This study investigates the influence of applied voltage and electrode gap on the efficiency of ozone generation in a plasma-based system. Ozone, as a strong oxidizing agent, plays a critical role in various industrial applications, including air and water purification. The objective of this research was to analyze the relationship between applied voltage, electrode gap, and ozone production efficiency. Discharges have been characterized with electrical methods. A plasma discharge system was constructed with electrode gap distances of 0.5 mm, 1.0 mm, and 1.5 mm. The applied voltage was varied between 9.38 kV and 17.20 kV at intervals of thirty seconds. The findings revealed a positive correlation between applied voltage and ozone concentration, with higher voltages leading to increased ozone production. Specifically, ozone concentrations ranged from 99 ppm to 786 ppm for a 0.5 mm gap, 56 ppm to 555 ppm for a 1.0 mm gap, and 20 ppm to 395 ppm for a 1.5 mm gap. The result further demonstrated that ozone production decreases as the electrode gap widens, highlighting the impact of electrode gap distance on ozone generation. Additionally, non-linear trends were observed, where ozone concentration increased moderately with smaller voltage changes and more significantly with higher voltage increments.
