Summary:The article deals with a novel method of preparing nanotechnology-based photocatalysts suspended in aqueous solution and their application for water treatment from chloro-organic compounds and bacteria. The nanophotocatalysts were synthesized in the electrolytic cell with titanium and graphite electrodes. Under the natural ultraviolet radiation the nanophotocatalysts form OH-radicals in presence of water molecules of natural moisture during daylight hours; OH-radicals react with organic substances. Results of laboratory tests of the method conducted with E. Coli, methyl orange (MeO), methyl blue (MeB) and polychlorinated biphenyls (PCBs) in a Petri dish under sunlight radiation are described. Experiments have shown that decoloration of MeO and MeB occurs in 15-60 minutes, and the destruction time of PCBs is about 6-8 hours.
