在本研究中，多孔硅基共价有机框架纳入复合材料使用溶剂热反应和以下湿浸渍法制备。采用扫描电镜、傅里叶变换红外光谱、X射线粉末衍射等多种表征手段对复合材料的表面形貌、热稳定性和孔结构进行了表征。采用间歇实验，考察了吸附时间、溶液温度和硝酸溶液对复合材料吸附模拟高放废液中钯的影响。
In the present study, a porous silica-based covalent organic framework incorporated composite was prepared using a solvothermal reaction and the following wet-impregnation method. Multiple characterization methods including Scanning electron microscope, Fourier transform infrared spectroscopy, X-ray powder diffraction confirmed the surface morphology, thermal stability, and pore structure of the as-prepared composite. The adsorption performances of the prepared composite toward palladium [Pd(II)] from simulated high-level liquid waste were systematically investigated using batch experiments under the effect of contact time, solution temperature, and nitric acid solution.
