Abstract
Macroporous chelating resins containing polyol groups (RGB) were prepa red by the reaction of poly(glycidyl methacrylate) beads with 2-amino- 2-hydroxymethyl-1,3-propanediol, and the behavior of the resulting RGB in the uptake of boric acid was studied. The RGB exhibited high affin ity for boric acid in the pH range of 5 to 9 and took up boric acid se lectively from geothermal power waste solutions in which various miner als were contained. The boric acid adsorbed on the RGB was easily elut ed with 1 mol/dm(3) hydrochloric acid.
