| 摘 要： | 以废玻璃为原材料, 制备表面修饰多孔微晶玻璃(Thio-aminopropyltriethoxysilane-modified porous glassceramics, TAMPG), 实现对水溶液中钯(II)的高效吸附分离。通过在废玻璃制成的多孔微晶玻璃上负载有机配体2-噻吩甲醛、2-巯基苯并咪唑和2-巯基苯并噻唑, 得到新型吸附剂TAMPG-1, TAMPG-2和TAMPG-3, 同时对钯(II)吸附过程的pH 值、温度、初始浓度和吸附时间等条件进行优化。由于原材料廉价易得, 吸附性能良好, 可循环使用, 同时具备优良的选择性和稳定性, 所以表面修饰多孔微晶玻璃既可以高效地分离钯(II), 也能产生良好的经济效益。

| Abstract: | Thio-aminopropyltriethoxysilane-modified porous glass-ceramics (TAMPG) were prepared through reuse of waste glass for efficient palladium (II) separation from wastewater. Novel TAMPG-1, TAMPG-2, TAMPG-3 were obtained by immobilizing organic ligands 2-thiophene formaldehyde, 2-mercaptobenzimidazoles and 2-mercaptobenzothiazole onto the surface of porous glass-ceramics made from waste glass. Optimal conditions for effective palladium (II) adsorption were investigated with respect to pH, temperature, initial concentration and contact time. Owing to cheap raw materials, good adsorption properties, great recycling potential, excellent selectivity and stability, an economically viable method was proposed for efficient palladium (II) separation from wastewater. |
