METHOD OF ELECTROACTIVATION OF AQUEOUS SODIUM SALT SOLUTIONS Russian patent published in 2015 - IPC C02F1/46 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of aqueous solution processing and can be used for obtaining electroactivated aqueous solutions of sodium salts. The method includes the processing of initial solutions by electric current at an installation with a diaphragm electrolyser with their loading into cathode and anode chambers. As the initial solution used is a diluted solution of disodiumphosphate or sodium sulphate with the concentration of 0.09-0.22%, processing is carried out in the electrolyser, representing a general reservoir of a cylindrical type with a bottom and open top, in which an internal cup-semicylinder with a tarpaulin window on the flat side, serving as the diaphragm, is inserted, a titanium anode with a coating of titanium and ruthenium oxides is located in the internal cup, forming an anode chamber, a stainless steel cathode is located in the general reservoir, forming a cathode chamber; the ratio of anolyte and catholyte volumes constitutes 1:1.7-2.0, with the processing being performed with the specific consumption of the electricity amount of 0.208-0.243 ampere-hours per 1 l of catholyte and anolyte.

EFFECT: reduction of the salt and electricity amount consumption, technology simplification, process control.
