摘要: 以正硅酸四乙酯为硅源，五倍子单宁（PT）为吸附源，戊二醛为交联剂，通过一步法制备了三维五倍子单宁/有序介孔二氧化硅的复合材料1.2-PT-10-KIT-6。采用透射电镜、小角X射线衍射、红外光谱、N₂吸附-脱附对其进行表征，此材料具有类似KIT-6的三维立方的结构。在pH=10条件下，对镓的最大吸附量达到186.73 mg/g，符合Langmuir单分子层吸附，相关系数R²=0.99。在Ga/Ge与Ga/As的二元体系中，选择性因子均大于1.5，能够实现对镓的选择性分离。吸附机理为酚羟基与Ga（OH）₄^-之间发生离子交换作用，O原子与Ga配位形成螯合物。经过6次再生后，镓的回收率仍大于95%，循环再生能力较好。

Abstract: A three-dimensional gallnut tannin/ordered mesoporous silica composite 1.2-PT-10-KIT-6 was prepared by one-step method with tetraethyl orthosilicate as silicon source, gallnut tannin as adsorption source and glutaraldehyde as crosslinking agent. Transmission electron microscopy, small angle X-ray diffraction, N₂ adsorption and Fourier transform infrared spectroscopy were used to characterize the materials. All the materials had a three-dimensional cubic structure similar to KIT-6. The maximum adsorption capacity of gallium reached 186.73 mg/g at pH 10, which conformed to Langmuir monolayer adsorption, and the correlation coefficient R² was 0.99. In the binary system of Ga/Ge and Ga/As, the selectivity factor was more than 1.5, which could realize the selective separation of gallium. The adsorption mechanism was ion exchange between phenolic hydroxyl group and Ga(OH)₄^- and the O atom on phenolic hydroxyl group chelated with Ga(OH)₄^- to form a chelate. After six regeneration cycles, the recovery was over 95%.
