Abstract
For the purpose of investigating the effect of a wide discharge gap (4 mm) on ozone generation, a UV light absorption measurement technique has been u sed to determine the spatial distribution of ozone concentration. A glow di scharge at atmospheric pressure was produced by a double discharge method w ith a pair of metal-to-metal electrodes. Efficient and uniform ozone genera tion has been accomplished. The obtained ozone concentration near the catho de is about 1.25 times higher than that at the center of the main gap. The rate constant k(1) for O + O-2 + M -->(k1) O-3 + M yields the values of (2. 0-2.7) x 10(-34) cm(6) molecule(-2) s(-1) from the ozone growth curve measu red using the wavelength of 254 nm.
