Evaluation of Ozone Oxidation and UV Degradation of Dimethylnitrosamine.

Abstract

Dimethylnitrosamine was detected in the wastewater leaving Holston Army ammunition Plant. The wastewater from the ammonia stripping column was treated with (1) ozone, (2) ultraviolet light, and (3) a combination of both ozone and ultraviolet light. Ozone alone does not degrade DMN. Ultraviolet degrades DMN yielding first-order kinetics with a rate constant of 1/0.025 min. A special run using UV was performed on the feed to the ammonia stripping column and it also yielded first-order kinetics with a rate constant of 1/0.044 min. (Author)
