摘要
Macroporous chelating resins containing polyol groups (RGB) were prepared 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 affinity for boric acid in the pH range of 5 to 9 and took up boric acid selectively from geothermal power waste solutions in which various minerals were contained. The boric acid adsorbed on the RGB was easily eluted with 1 mol/dm(3) hydrochloric acid.
