Abstract

Boron removal process using electrodialysis method combined with bipolar membrane water splitting reaction was investigated. By using bipolar membrane electrodialysis, pH value of boron contained solution will immediately increase and the dissociation reaction of boric acid into borate ions was enhanced. Therefore, boron can be effectively removed from boron contained solution. Experimental results confirm that bipolar membrane electrodialysis has an advantage over existing electrodialysis. Effect of initial concentration was investigated. It was confirmed that energy requirement for boron removal increase when the initial boron concentration increase.
