| Abstract: | The sodium polyacrylate modified polyethersulfone pellets are prepared by the in-situ cross-linking method. The prepared spheres are characterized and confirmed by the infrared thermogravimetric analysis and scanning electron microscopy. The adsorption and removal ability of modified polyethersulfone pellets to copper ions is tested to characterize their adsorption and removal ability to heavy metal ions, and the adsorption and application ability of modified polyethersulfone pellets is further investigated by simulating adsorption column experiments. This experimental design is reasonable and the effect is obvious. It involves the preparation, characterization and adsorption performance test of modified polymer materials, which is suitable for engineering students. |
