中文摘要: 以壳聚糖(CTS)为基材,钼酸根离子为印迹离子,制备了一种新的CTS表面阴离子印迹凝胶球。以Mo(Ⅵ)的吸附量作为评价指标,对凝胶球的制备条件进行了优化。结果表明,当CTS质量分数为2%,凝固浴温度为20 ℃,钼酸铵和三乙醇胺的质量分数分别为2%和11%,热处理温度为60 ℃,洗脱剂NaOH的浓度为8.0 g/L时,所制备的凝胶球吸附性能较佳。与不添加印迹阴离子的壳聚糖凝胶球相比,这种CTS表面阴离子印迹凝胶球吸附容量有了大幅度提升。
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).
