| titleOfInvention | Polymer hydrogel for absorbing heavy metals and preparation method and application thereof |
| abstract | The invention belongs to the technical field of an absorption material, and particularly relates to polymer hydrogel and a preparation method and application in absorption of heavy metal ions. The polymer hydrogel is a three-dimensional network polymer which is not dissolved in water and is strongly swelled in the water, and is generated by radiation copolymerization of two monomers of hydroxyethyl acrylate (hydrophilic glass-state monomer) and 2-acrylamide-2-methylpropanesulfonic acid. The polymer hydrogel has the structural and property characteristics of low degree of cross linking, high swelling rate, property of not being dissolved in the water, strong water absorbing capability and good water-retaining property, can not be dehydrated under the condition of pressurization after absorbing the water, and simultaneously, has the basic characteristics of a general polymer compound. In the invention, the polymer hydrogel prepared by the radiation copolymerization contains multi-functional groups for absorbing the heavy metals, and has good absorption property to lead, cadmium and other heavy metals. In addition, the synthetic method is simple, the operation is simple, the reaction process is free from other impurities, and a product can be ensured to be pure. |
