| titleOfInvention | Method of producing sodium arsenate |
| abstract | FIELD: chemistry. n SUBSTANCE: method of producing sodium arsenate involves electrolysis of water-alkaline solutions. Iron (III) hydroxide undergoes electrodialysis separation from sodium arsenate and arsenite, and spent iron hydroxide, which contains sodium arsenate and arsenite, is treated with 0.5 n Na 2 CO 3 solution. The anode chamber is filled with 0.01 n sodium hydroxide solution and current density is set at 0.069 A/cm 2 . The process takes place in a double-chamber electrolysis cell with an anion exchange membrane for 1.5 hours. n EFFECT: invention simplifies the process of obtaining sodium arsenate, increases purity of the obtained product based on non-waste technology owing to recycling of arsenic from spent iron hydroxide residue. n 2 tbl, 1 ex |
