| description | The invention relates to a preparation method of a polyurethane foam adsorption material. Polyethyleneimine is modified to a foam surface by a solution reaction method, glutaraldehyde is added to serve as a crosslinking agent to prepare the polyethyleneimine functionalized polyurethane foam adsorption material, and the material can be used for adsorbing and separating heavy metal ions and dyes insewage. The preparation method is simple, the cost of the adsorption material is reduced, waste polyurethane foam can be recycled, and a novel efficient low-cost adsorption material is provided for waste water treatment.
本发明涉及种聚氨酯泡沫吸附材料的制备方法，采用溶液反应法将聚乙烯亚胺修饰到泡沫表面，然后加入戊二醛作为交联剂，制备出了聚乙烯亚胺功能化的聚氨酯泡沫吸附材料，可用于吸附分离污水中的重金属离子和染料。本发明制备方法简单，降低了吸附材料的成本，既解决了废弃聚氨酯泡沫的回收利用问题，又为废水处理提供了种新型高效低成本的吸附材料。 |
