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.

在本研究中，使用溶剂热反应和以下湿浸渍法制备了多孔二氧化硅基共价有机骨架复合材料。包括扫描电子显微镜、傅里叶变换红外光谱、X 射线粉末衍射在内的多种表征方法证实了所制备复合材料的表面形貌、热稳定性和孔结构。在接触时间、溶液温度和硝酸溶液的影响下，使用批量实验系统地研究了制备的复合材料对来自模拟高放废液的钯 [Pd(II)] 的吸附性能。
