Title:
METHOD OF DESALINATING BORON-CONTAINING SOLUTION
Document Type and Number:
WIPO Patent Application WO/2014/064754
Kind Code:
A1
Abstract:
This method uses an ion exchange resin to decrease salts other than boron from a boron-containing solution containing anions such as chloride ions. In the method, two anion exchange resin-packed columns, each packed with a free base form of weak base anion exchange resin, are arranged in series at the outlet of a cation exchange resin-packed column packed with an H-type strong acid cation exchange resin. The boron-containing solution is passed from the inlet of the cation exchange resin-packed column, the density of anions, such as chloride ions, in the outlet solution from the anion exchange resin-packed column nearest the cation exchange resin-packed column is monitored, and the desalination process is continued until the breakpoint of the anions, such as chloride ions, is detected.
