| Abstract: | There are several routes to produce glyoxal,and the purification techniques are somewhat different.In the process of producing glyoxal by means of nitric acid oxidation, the main components to be removed in the product are nitric acid and acetic acid.This paper discusses mainly the applications of electrodialysis and electrodeionization techniques to purify glyoxal aqueous solution.Some other methods are also introduced. |

| Keywords: | glyoxal purification electrodialysis electrodeionization technology |
