Abstract

Photoacoustic spectroscopy was used to analyze the transport of ozone through the air/water interface. Experimental results showed that the ozone transport rate is similar to rates measured for other gases of low solubility and low reactivity. The transport rate increases with increasing pH. The decomposition rate of ozone was studied in solutions. The decomposition rate also depends on the pH of the solution, and in high pHs both the deposition velocity and the decomposition rate constant of ozone have larger values. The value of the deposition velocity (Kd) is 3.7 ± .9 x 10-3 cm/sec and the decomposition rate constant is 5.3 ± 0.6 x 10-5 sec-l for distilled water. For ocean water, the respective values are 5.2 ± 0.4 x 10-3 sec-l and 7.8 ± 0.4 x 10-4 cm/sec respectively.
