摘要：Borate ions which are dissolved at low concentration in water or aqueous liquids can be isolated using a hydroxide or hydrated oxide of a rare earth element as adsorbent in an effective manner. If water containing borate ions is brought into contact with this adsorbent, borate ions are isolated by adsorption. The adsorbent containing the adsorbed borate ions is subjected to a desorption treatment and regenerated for reuse with the aid of a desorption solution, the pH of which is adjusted to about 2 to about 4 or to about 12 to about 14.
