摘要
PURPOSE:To remove salt from an org. material contg. salt by using an electrodialysis cell installed with ion exchange membranes constituted by arranging alternately plural numbers of groups of cation exchange membrane and anion exchange membrane each comprising = two membranes arranged successively. CONSTITUTION:Salts in an org. material is transferred in the form of ion by the electrodialysis to the first concentration chamber 6 through a cation exchange membrane 3 and an anion exchange membrane 4, and then desalted further in the second concentration chamber 7. Thus, the org. material in the desalting chamber 5 is desalted and purified. On the other hand, the concn. of salt in the circulating liquid for the second concentration chamber 7 is increased, therefore, the salt concn. is adjusted not to exceed the salt concn. in the circulation liquid for the first concentration chamber 6 by returning a part of the liquid to the desalting chamber 5, and the org. material leaked into the first concentration chamber 6 is recovered.
