| Abstract: | We studied the relationship between desalting rate of different types of ion selective permeable membranes and iminodiacetic acid loss percentage at isoelectric point in recovery of iminodiacetic acid from wastewater by electrodialysis. The effective way to control concentration diffusion was decided. The results show that the iminodiacetic acid wastewater can be treated effectively by electrodialysis method. The desalting rate is > 96% and the iminodiacetic acid loss percentage is < 0.6%. |
