Paper Title:
Preparation of Xanthan Gum-G-N-Vinylpyrrolidone by Radiation and Adsorption Property of Phenol and Polyphenol
  Abstract

Simultaneous radiation grafting method(60Co γ as radiation source)was used to prepare xanthan gum - graft - N-Vinypyrrolidone (XG-g-NVP). FT-IR spectra showed that grafting reaction occurred in NVP Vinyl part and lactam structure was retained. Thermo gravimetric analysis showed that, XG-g-NVP enhanced thermal stability of xanthan gum. XRD showed the crystallinity increased after grafting. At the grafting yield of 623%, XG-g-NVP had the maximum adsorption capacity of phenol and TP, the adsorption amount of which were 0.76 g/g and 2.85 g/g respectively. PH value had the different effects on the adsorption of phenol and tea polyphenols by XG-g-NVP.
