摘要：

Iminodiacetic acid (IDA) is a key intermediate for the synthesis of glyphosate, a broad-spectrum herbicide. In the main current synthetic methods IDA is obtained as its sodium or potassium salts. The recovery of IDA in high yield and purity is not an easy task if current procedures are used. Both problems can be overcome by using electrodialysis. Thus, IDA with a purity higher than 99.2% was obtained. Faradaic and material yields were 90.5% and 99.9%, respectively.
