Ozone treatment of hydrazine-containing water solution

The results of experimental investigation on decomposition of 0.1 and 0.2% hydrazine-containing standard test water solution by bubbling ozone-oxygen mixture through the water solution are presented. It was shown, that the time of hydrazine decomposition to the concentration lower than the MPC under the influence of ozone concentration of 15...40 gO3/m3 was 10 min for 0.1% hydrazine-containing water solution and 30...45 min for 0.2% hydrazine- containing water solution.
