Electrodialysis is a widely used industrial technique for the removal of salts from aqueous solution. The process involves the conversion of salts into their corresponding acid and base components; e.g., sodium chloride becomes hydrochloric acid and sodium hydroxide. Many of the residues generated in plutonium recovery operations are in the form of chloride and nitrate salts. Using electrodialysis to convert these salts back into their corresponding acid and base components results in the production of a decreased amount of waste. Furthermore, with recycle of the acid and base generated, electrodialysis results in a decrease in the quantity of reagents necessary to recover and purify plutonium.
