摘要
本文采用溶胶-凝胶法制备季铵化壳聚糖(QCS)/钛酸四丁酯(TBT)杂化膜。利用FT-IR,TGA对所制备的杂化膜进行测试表征。并考察其对罗丹明B(RB)的吸附性能。结果表明:最佳吸附条件为:TBT含量为15%,吸附时间为80min,p H值为4,RB的初始浓度为100mg·L-1,温度为50℃。在此条件下,该杂化膜对RB的吸附量为22.13mg·g^(-1)。
Organic-inorganic hybrid membranes were synthesized with quaternized-chitosan (QCS) and tetrabutyl titanate (TBT) through the method of sol-gel reaction. The prepared samples were characterized by FT-IR, TGA. It's adsorption ability for rhodamine B (RB) was investigated. The results show that the optimum adsorption condition: the mass fraction of TBT is 15%; adsorption time is 80 min; pH values 4; the initial mass concentration of RB is 100mg·L^-1; temperature is 50℃ Under this condition, the RB adsorption capacity of the membrane is 22.13mg·g^-1.
