Abstract Reverse-osmosis (RO) has become a prevailing technology for seawater desalination. While RO removes the majority of ions in seawater, the removal of small, uncharged contaminants remains challenging. Boron existing as uncharged boric acid (B (OH)3) in seawater is partially removed during the RO process, requiring further treatment if the desalinated seawater will be used for certain crop irrigation. Boron removal efficiency is significantly improved under a high pH condition where non… Expand
