A process is provided for separating, concentrating and recovery of boron
compound from aqueous solution containing boron, strongly dissociated
anions and some cations. The process specifically integrates
electrodialysis with ion exchange to selectively separate boron from
aqueous solution that contains a wide concentration range of boron,
strongly ionised anions such as chloride, nitrate and sulfate, and
cations like lithium. The process is adapted for controlling boron
concentration in an industrial process, for the recovery or purification
of boron and some cations like lithium form aqueous solutions, and for
wastewater treatment.
