The novel chelating adsorbent has been synthesized by functionalization of monodisperse-porous poly(glycidyl methacrylate-co-ethylene dimethacrylate) particles with N-methylglucamine (NMDG) as a boron selective ligand. The resulting resin can adsorb boron in almost all pH range (pH 4-10) and its maximum capacity is ca. 12 mg/g. The adsorption behavior of poly(GMA-co-EDM)NMDG resin obeyed Langmuir isotherm well.
