抄録

The adsorptive removal of borate-boron from an aqueous solution using silica gel was studied using a batch equilibration technique. The effects of the pH and metal ions, such as alkali metal and alkaline earth metal, were clarified. The boron adsorption efficiencies increased with increasing the pH and the concentration of alkaline earth metal ions, and their maximum adsorptions were obtained at pH 10-12 in solutions containing calcium ion. The adsorption data obtained by changing the boron concentration and the adsorbent dosage were well represented by the Freundlich isotherm model.
