Selective Heavy metal adsorbent in industrial waste water and preparation method thereof

摘要

The present invention relates to a natural pulp material having a heavy metal adsorption layer containing spherical hydrogel beads containing chitosan and gelatin and a method for manufacturing the same, wherein the selective heavy metal adsorption material comprises a heavy metal adsorption layer containing spherical hydrogel beads By doing so, there is an advantage that the heavy metal adsorption ability is also excellent. In addition, the selective heavy metal adsorption natural material according to the present invention is a heavy metal adsorption composition prepared by dispersing hydrogel beads in a heavy metal adsorption composition, and the first stock solution is put on the mesh of the rotating jangmang paper machine to facilitate heavy metal adsorption. An adsorption layer can be formed.
