Abstract

The invention provides a method for preparing a multifunctional chelating ion exchanging fiber. The method comprises the following steps of: taking synthetic fiber or blended fiber of synthetic fiber, cotton and hemp as substrate fiber, soaking in an amino resin solution and obtaining tertiary amino group functional fiber; and then reacting the tertiary amino group functional fiber with 5-(chloromethyl) salicylaldehyde and amino-compound in turn so as to lead quaternary ammonium and salicylaldehyde shrink amino compound structure units to the functional fiber to obtain the multifunctional chelating ion exchanging fiber.

Description

technical field [0001] The invention relates to a chelating ion exchange fiber, in particular to a chelating ion exchange fiber formed by coating fibers with chelating resins, which has the functions of detection, analysis, separation, enrichment and exchange of various water-based metal ions, and belongs to functional material field. technical background [0002] Ion exchange fiber is a cationic or anionic group on the fiber skeleton that interacts with the charge of anions or cations in the medium through Coulomb attraction to produce anion or cation adsorption and separation functions. Chelating fiber is a chelating functional group with N, O, S, P coordination atoms in the fiber to form a coordination bond with metal ions to form a chelate, thereby producing the detection, analysis, and separation of cations or anions. , Enrichment function. At the same time, ion exchange fibers with chelating groups are called chelating ion exchange fibers. Chelating ion exchange fib...
