Cellulose xanthogenates, derived from the straw of Eichhornia crassipes, were prepared as adsorbents for heavy metals by CS 2 sulfonation and magnesium substitution after degumming with alkali, self-isolated A 1 strain and pectase, respectively. The effects of three degumming treatments were compared by functional groups analysis, surface morphology and surface element composition...
A new environmental functional material-quaternary ammonium cationic cellulose (QACC) was synthesized in this paper. Preparation conditions were optimized. The modified cellulose was fully characterized by fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM). The stability of QACC was studied. Adsorption rules of water-soluble persistent organic...
