Abstract :A novel degradable adsorbent for the removal of heavy metal ions from waste water, a hyperbranched aliphatic polyester grafted cellulose insert ignore into journalissuearticles values(HAPE-Cell);, was successfully prepared by the simple one-pot method for the first time. The hyperbranched aliphatic polyester was grafted from the surface hydroxyl groups of natural cotton fibers via the solution polycondensation of the AB2 monomer, 2, 2-bisinsert ignore into journalissuearticles values(hydroxymethyl);propionic acid insert ignore into journalissuearticles values(bis-MPA);, with the catalysis of p-toluenesulfonic acid insert ignore into journalissuearticles values(p-TSA);. The HAPE-Cell was characterized by elemental analysis, Fourier transform infrared insert ignore into journalissuearticles values(FT-IR); spectroscopy, X-ray diffraction insert ignore into journalissuearticles values(XRD);, and scanning electron microscopy insert ignore into journalissuearticles values(SEM);. The adsorption properties of the HAPE-Cell towards the heavy metal ions insert ignore into journalissuearticles values(Cuinsert ignore into journalissuearticles values(II);, Hginsert ignore into journalissuearticles values(II);, Zninsert ignore into journalissuearticles values(II);, and Cdinsert ignore into journalissuearticles values(II);); were also preliminarily investigated.
