titleOfInvention | Polyacrylonitrile-hydroxyurea chelate fiber and synthetic method and application thereof |
abstract | The invention discloses polyacrylonitrile-hydroxyurea chelate fiber, which has the structural formula as follows: the invention also discloses a synthetic method thereof, which comprises the following steps: adding polyacrylonitrile fiber (as a matrix), hydroxyurea (as a ligand) and sodium carbonate into a solvent, and heating to 110-140 ℃ under the microwave condition to react for 5-20 min; and washing the obtained polymer with deionized water, and drying to obtain the polyacrylonitrile-hydroxyurea chelate fiber. The invention also discloses the application of the polyacrylonitrile-hydroxyurea chelate fiber: selectively adsorbing Cu (II); the method is used for detecting the Cu (II) content in the vegetables. |
