Abstract

A fiber capable of forming a metal chelate and a process for producing the same are disclosed, wherein the fiber is characterized in that at least one metal chelate-forming compound selected from the group consisting of aminocarboxylic acid. aminocarboxylic acid, thiocarboxylic acid and phosphoric acid. which are reactive with a glycidyl group, is bonded to a molecule of a synthetic fiber through a crosslinkable compound having a reactive double bond and a glycidyl group in its molecule. The chelate-forming fiber is excellent in capturing harmful heavy metal ions and can be easily produced in a simple and safe way at a low cost.

Description

technical field

[0001] The present invention relates to a novel metal chelate forming fiber, its production method, a metal ion trapping method using the fiber, and a metal chelate fiber. Such chelate-forming fibers, for example, can selectively and efficiently adsorb trace amounts of metal ions in water, especially harmful heavy metal ions such as copper, zinc, nickel, and cobalt, even in low pH regions, and can be widely and effectively used It is used in the purification of industrial wastewater or drinking water and oil, etc., and the metal chelate fiber formed by chelating the fiber and the metal can be effectively used as various catalysts, deodorizing and deodorizing agents by utilizing the activity of the chelated metal. , antifungal agents, antibacterial and fungicides, antistatic materials, electromagnetic wave shielding materials, shading materials, colored clothing, decorations, fertilizers and metal rust inhibitors, etc. Background technique
