PROBLEM TO BE SOLVED: To provide a fibrous metal chelate material which exhibits excellent trapping performance against harmful heavy metal ions and the like, is easy to incinerate, etc., and can be manufactured easily, safely and at low cost. And the development of its manufacturing method and its utilization technology. SOLUTION: In the fiber molecule of natural fiber or regenerated fiber, At least one metal selected from the group consisting of aminodicarboxylic acids, thiocarboxylic acids and phosphoric acids having reactivity with glycidyl groups via a crosslinking reactive compound having a reactive double bond and a glycidyl group in the molecule Disclosed is a metal chelate-forming fiber to which a chelate-forming compound is bonded and a method for producing the same, and a method for trapping metal ions using the fiber, and further provide a metal chelate fiber that enables the properties of the metal to be effectively utilized. I do. |
