合成了含醚键的多羟基大孔螯合树脂,通过添加极性单体的方法提高了树脂的机械强度和动力学性能。讨论了合成条件及树脂对硼酸的吸附,解吸性能。结果表明,在中性、弱碱性条件下树脂可较好地吸附硼酸,并可用10％硫酸或5％盐酸洗脱。 Polyether polyol-containing macroporous chelate resins were synthesized. The mechanical properties and kinetics of the resins were improved by adding polar monomers. The synthesis conditions and the adsorption and desorption properties of boric acid by resin were discussed. The results show that the resin can adsorb boric acid well under neutral and weak alkaline conditions and can be eluted with 10% sulfuric acid or 5% hydrochloric acid.
