In our previous report, a study was made on the extraction of boron adsorbed inferric hydroxide by using the solution of sodium hydroxide or hydrochloric acid.
In this report, an investigation was conducted on the separation of boron in the extracted solutions by means of the bathwise operation of ion exchange.
The mixture of a cation exchanger, Amberlite IR-120 and an anion exchanger, Amberlite IR-45 was used for the removal of ions excluding boron. After the filtration, a proper quantity of a strong base anion exchanger, Amberlite IRA-400 was applied for the adsorption of boron and traces of other anions.
The recovery of boron to the strong base anion exchanger was found to be about 92%.
