FIBROUS METAL-ADSORBING MATERIAL

摘要

Provided is a fibrous adsorbing material used for the adsorption and recovery of metals in a solution, which is a fibrous metal-adsorbing material that can be produced using existing production facilities without using special facilities or complicated operations, has high durability, is easy to diversify, and can be processed into various forms. The fibrous metal-adsorbing material is produced by a) a step of preparing an acrylate polymer having a large number of glycidyl groups in the molecule, b) a step of kneading a low-melting-point fiber matrix polymer therewith, c) a step of making the resulting mixture into a fibrous form by an melt-blend spinning method, and d) a step of allowing a long-chain ligand having an amino group or an imino group to react with glycidyl groups on the fiber surface to introduce a metal-adsorbing functional group. The fibrous metal-adsorbing material has high durability, is easy to diversify, and has various forms.

1. A fibrous metal-adsorbing material characterized by being produced by spinning an acrylate polymer having a large number of glycidyl groups and a low-melting-point fiber matrix polymer having a melting point of 200° C. or less by a melt-blend spinning method into a fibrous form, and then allowing a long-chain ligand having an amino group or an imino group to react with glycidyl groups on a fiber surface to introduce a metal-adsorbing functional group.
