Abstract：
 The invention discloses a method for reclaiming organic acid from organic solvent in chemical mass transfer separation technology field. the organic solvent loaded with organic acid is mixed with aqueous solution of the organic acid salt and they are produced into latex liquid, then the latex and the aqueous solution containing the organic acid enters the negative chamber and positive chamber of the electrodialysis device, it realizes the synchronous extraction and condense of organic acid in the aqueous solution through electric transfer and electrode reaction. Compared with current technology, it has a high energy utilization rate, and low cost and side product.
