Selective boron extraction by polymer supported 2-hydroxylethylamino propylene glycol functions

It was observed that, more than 95% of boron is extracted by this resin from very dilute H3BO3 solution (100 ppm initial concentration) in less than 30 min of contact time. Splitting of sorbed boron can be achieved by simple acid leaching (4 M HCl) and regenerated by NaOH (0.1 M) solution.
