PROBLEM TO BE SOLVED: To provide refining equipment and a refining method of acid radical containing boron eluate, which enables to obtain a highly pure boric acid solution with a simple process and at a lower facility cost. SOLUTION: In an ion exchange tower 50, an anion exchange resin is packed after being selected from the group of an OH-type adjusted I-type strongly basic anion exchange resin, an OH-type adjusted II-type strongly basic anion exchange resin, and an OH-type adjusted weakly basic anion exchange resin. The acid radical-containing boron eluate passes through the ion exchange tower to remove acid radical and to obtain the highly pure boric acid solution. |
