FIELD: technological process.
SUBSTANCE: invention may be used in all fields of engineering, in which application of disinfectant solutions is required, in particular, in medicine, food industry and others. Method of disinfectant preparation includes supply of water solution of alkaline metal carbonate in anode chamber of diaphragm electrochemical cell with cylindrical coaxial electrodes and coaxial ceramic ultra-filtering diaphragm, supply of fresh water in cathode chamber of the same cell and disinfectant drain from anode chamber. Solution of alkaline metal carbonate and water are supplied in anode and cathode chambers of cell with counter-flow. Process is carried out during current conduction via diaphragm mainly with alkaline metal ions. Disinfectant prepared by treatment of water solution of alkaline metal carbonate with concentration of 0.2-2 g/l in anode chamber of electrochemical diaphragm cell with coaxial electrodes and coaxial ultra-filtering ceramic diaphragm, contains peroxide compounds that are in metastable condition and has pH of 6-7.
EFFECT: invention allows to prepare efficient disinfectant that does not contain chlorine, in required quantity at site of consumption with reduction of costs for its manufacturing and usage.
