Abstract The uptake into γ-zirconium phosphate by batch method of 2,2′-bipyridyl, 2,4′-bipyridyl, and 4,4′-bipyridyl in ethanol:water solutions of various solvent ratios has been studied. The obtained materials were examined by powder X-ray diffraction (PXRD), thermogravimetric and differential thermal analysis (TG-DTA) techniques, and UV-vis, IR and Raman spectroscopy. It has been found that the ligand
摘要 研究了 2,2'-联吡啶、2,4'-联吡啶和 4,4'-联吡啶在不同溶剂比例的乙醇:水溶液中通过间歇法吸收到 γ-磷酸锆中。通过粉末 X 射线衍射 (PXRD)、热重和差热分析 (TG-DTA) 技术以及紫外-可见光、红外和拉曼光谱对所得材料进行检查。已经发现,进入交换剂中的配体含量取决于批次温度、接触批次中的配体:交换剂比率、乙醇:水溶剂比率和二胺中的异构氮位置。配体 2,2'-联吡啶在乙醇:水的比例为 1:9 时获得了最高的吸收。
