FIELD: chemistry.
SUBSTANCE: invention relates to disinfectant compositions and specifically to a highly stable acidic aqueous solution, a method and apparatus for production thereof. The solution is prepared using a fluid medium treatment apparatus having at least one chamber (7), at least one anode (4) and at least one cathode (3) inside the chamber (7). The anode (4) and the cathode (3) are at least in part made from a first metallic material. At least one of said at least one cathode (3) and anode (4) have a coating with nanoparticles (5) of one or more metals.
EFFECT: obtained electrolytic acid water has high stability of its disinfecting action for a relatively long period of time, has low cost of production and is easy to produce.
