FIELD: chemistry.
SUBSTANCE: method comprises electrolysis of an aqueous solution containing salicylic acid at a current density of 0.1 A/cm2 and air under pressure 0.1-0.7 MPa, leading to dilution of the hydrogen-oxygen mixture of air with nitrogen.
EFFECT: increase electrolyzer safety operation pressure by using air pressure to create, rather than pure oxygen, as well as improving the efficiency of wastewater containing salicylic acid.
