| Abstract: |
| A new chitosan(CTS) gel beads imprinting anion Mo(Ⅵ) was prepared by droping CTS solution into the mixed solution of ammonium molybdate and triethanolamine(TEA). The preparing parameters were optimized using adsorption capacity of gel beads for Mo(Ⅵ) as evaluation index. The results show that the optimal conditions for preparing CTS gel beads imprinting anion Mo(Ⅵ) with best adsorption capacity were CTS mass fraction of 2.0%, Mo(Ⅵ) mass fraction of 2.0%, TEA mass fraction of 11%, 60 ℃ for heat treatment, and 10.0 g/L sodium hydroxide as eluant. Compared with CTS gel beads without anion Mo(Ⅵ) imprinting, the new material promotes substantially the adsorption capacity for Mo(Ⅵ). |
