Abstract
751,856. Electrodialytic decomposition of salt solutions. PERMUTIT CO., Ltd. March 29, 1954 [April 7, 1953], No. 9419/53. Class 41. [Also in Group I] An aqueous effluent containing an acid is passed through an anion exchange material to take up the anions of the acid; these anions are removed in salt form from the anion exchange material during regeneration; and the salt is then electrolysed in a cell made up of two or more compartments separated from one another by one or more ion exchange diaphragms, to produce the acid. As shown, an effluent containing phosphoric acid is passed .through a bed of anion exchange material 3- the material being in the hydroxyl state-as shown by the dotted lines. Caustic soda is then passed through the bed to regenerate it and displace the phosphate anions taken up. The effluent regenerant is then electrolysed in the centre compartment 7 of a three compartment cell, the diaphragm 14 being a cation exchange diaphragm and the diaphragm 16 being an anion exchange diaphragm. Caustic soda is formed in the cathode compartment 4 and phosphoric acid in the anode compartment 5. Hydrogen and oxygen are liberated at the cathode and anode respectively. A two-compartment cell divided by an anion exchange or cation exchange diaphragm can also be used; in the former case the effluent regenerant is placed in the cathode compartment and in the latter case in the anode compartment for electrolysis. Specification 751,855 is referred to.
