摘要

以3-(三乙氧基硅基)异氰酸丙酯与壳聚糖为溶剂，在1-正丁基-3-甲基咪唑氯离子液体(w/w)中(~ 10% w/w)进行均相反应，采用两步法制备了两种壳聚糖硅杂化材料，产率为78-84%。结果表明，在室温下，这些新型杂化材料在24 h内可吸附5 × 10−4 M水溶液中高达95%的Fe3+。

Homogeneous phase synthesis of chitosan silica hybrid materials in ionic liquid medium and adsorption of Fe(III) from aqueous solutions

Two chitosan silica hybrid materials were prepared by a two-step process in 78–84% yields using the homogeneous phase reaction of 3-(triethoxysilyl)propyl isocyanate with chitosan dissolved in 1-n-butyl-3-methylimidazolium chloride ionic liquid (∼10% w/w), which was followed by NH₄OH catalyzed hydrolysis of triethoxysilyl groups and then sol-gel process. These new hybrid materials were shown to adsorb up to about 95% of Fe³⁺ from 5 × 10⁻⁴ M aqueous solution at room temperature in 24 h.
