摘要 |
The present invention relates to a method and related apparatus useful to electrodialytically convert salt to acid and/or base of improved purity. The apparatus comprises an electrodialytic water splitting apparatus comprised of at least one unit cell. Each cell comprises at least two means for splitting water. An intermediate compartment is between the two adjacent means for splitting water. At least one ion selective means is adjacent to at least one of the means for splitting water. An acid or base product compartment is between the ion selective means and the means for splitting water. There is an aqueous salt feed compartment, the ion selective means being between the salt feed compartment and the water splitting means. |
