ABSTRACT:
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.
