ASPECTS CONCERNING THE PHOTO- AND BIODEGRADATION OF BENZOTHIAZOLES IN AQUATIC COMPARTMENT

Abstract

With the scope to provide complete decomposition of benzothiazoles in water environment, two approaches have been applied including the photocatalytic and biodegradation processes. A new type of continuous-action flow-through photocatalytic reactor was developed, in which it is possible to combine the homogeneous and heterogeneous destruction of refractory organic pollutants. The interactions between the different components of the aminobenzothiazole-containing system under the conditions of photo- and biodegradation (light, iron, free and immobilized bacterial strain Rhodococcus rhodochrous) were analysed. The combined systems “Fe ± light +Rh.rhodochrous” are more effective than simple systems.
