Description

technical field [0001] The invention relates to an amidoxime group-containing polymer, a preparation method and application thereof, and belongs to the technical field of adsorption materials. Background technique [0002] Scattered metals (scattered metals) is referred to as SM, which is mainly for comprehensive recovery and regeneration from the by-products, leftovers and waste products produced in the production process of metallurgy, chemical industry, thermal power generation and other industries. Scattered metals have extremely important uses and are an important part of contemporary high-tech new materials. A series of compound semiconductors, electro-optical materials, special alloys, new functional materials and organometallic compounds composed of scattered metals and non-ferrous metals all need to use rare metals with unique properties. Although the amount is not large, it is very important. No. Therefore, it is widely used in contemporary communication technolo...
