Abstract

PURPOSE:To economically recover the mixture of hydrofluoric acid and nitric acid from waste acid with a simple apparatus, by carrying out electrolytic treatment using electrolysis vessel partitioned betwen cathode and anode by monovalent selective anion exchange membrane. CONSTITUTION:Inner part of the electrolysis vessel 1 made of anticorrosive steel plate, is divided into two rooms partitioning by the monovalent selective anion exchange membrane 2 and one room becomes a cathode room 3' by inserting the cathode plate 3 and another room becomes an anode room 4' by inserting the anode plate 4. Then, water or dilute nitric acid or dilute mixture of hydrofluoric acid and nitric acid, is injected in the room 4' and the waste mixture solution is injected in the room 3'. Next, electrolytic treatment is carried out by applying more than 2.5V of voltage between both electrodes 3, 4 and the mixture of hydrofluoric acid and nitric acid is recovered in the room 4'.
