Abstract
The invention relates to water purification from bacterial contamination by excited oxygen and can be used for water disinfection in various fields. The inventive water purification method consists in using a sensitiser and visual range radiation in the presence of oxygen, a cationic sensitiser being used in solution. Cationic dyes are used as sensitisers. Molecular oxygen or atmospheric oxygen is used as a source of active oxygen forms. The inventive method ensures an efficient and complete disinfection of bacterially contaminated waters.

Of the investigated catalytic pollutants, the LBC and the Harmonium are the least active, most likely due to the low yield of the active acid.
