| 摘 要： | 通过正硅酸乙酯（TEOS）与钛酸正丁酯（Ti（OC4H9）4）间的醇解反应和溶胶-凝胶法制备了一系列无机-有机杂化材料,并观察了Cu^2＋的浓度、体系的pH值等参数对Cu^2＋吸附性能的影响．结果表明：随着杂化材料中钛含量的增加,它们的比表面积随之增大．Cu^2＋吸附实验表明：该类杂化材料确实能够吸附Cu^2＋,而且不同比例的Si／Ti杂化材料对Cu^2＋的吸附能力不同．因此该类杂化材料能够用于废水中Cu^2＋的分离和回收,所以在废水处理等环境保护方面具有潜在的应用价值．

| Abstract: | A series of hybrid materials are synthesized by Sol-gel reaction and their adsorption behaviors for Cu^2＋ ion are investigated. The results show that, when the contents of titanium increase, the specific area of these hybrid materials increase accordingly. The absorption for Cu^2＋ reveals that the molar ratio of Si/Ti will have some effects on the absorption and desorption of Cu^2＋ , suggesting that these hybrid materials can be used to separate and remove the Cu^2＋. Based on these findings, it can be concluded that they have potential applications in such aspects as the separation and recycle of industrial wastewater. |
