Cotton as Precursor for the Preparation of Porous Cellulose Adsorbers

Autor: Daniel Baumert, Mathias Ulbricht, Alexandra Wittmar

Publikováno v: Macromolecular Materials and Engineering. 306:2000778

Natural biopolymer-based porous spherical adsorbers from cellulose have good efficiency for removal of metal ion pollutants from aqueous media. However, high purity celluloses, most commonly used as precursors for preparation of the adsorber spheres,
