Fluorescent polyester non-woven fabric, preparation method and application in metal ion detection

The invention provides a fluorescent polyester non-woven fabric material, a preparation method and application in metal detection, a rare earth fluorescent material is synthesized by using rare earth elements and ligands such as thiophene diketone and carboxylic acid, and grafting monomers such as acrylic acid and derivatives thereof or acrylamide and derivatives thereof are grafted to polyester through an ultraviolet grafting technology, so that the fluorescent polyester non-woven fabric material is obtained. The chemically bonded fluorescent polyester non-woven fabric is obtained by coordinating carboxyl and amide groups on a grafted monomer on the surface of a non-woven fabric such as polyamide and the like with the fluorescent material synthesized in the previous step, and can be applied to detection of copper ions in the fields of environmental analysis and food safety. 本发明提供一种荧光聚酯无纺布材料、制备方法及在金属检测中的应用，通过使用稀土元素与噻吩类二酮及羧酸等配体合成了稀土荧光材料，通过紫外接枝技术将丙烯酸及其衍生物或丙烯酰胺及其衍生物等接枝单体接枝到聚酯，聚酰胺等无纺布表面，接枝单体上面的羧基和酰胺基团与上一步合成的荧光材料配
