AB  - A novel bio-adsorbent was fabricated via grafting an amino-terminated 
      hyperbranched polymer (HBP-NH(2)) onto bagasse cellulose. The morphology and 
      microstructure of the HBP-NH(2)-grafted bagasse cellulose (HBP-g-BC) were 
      characterized and its adsorption capacity for Cr(VI) ions in aqueous solutions 
      was investigated. The rough surface structure of HBP-g-BC that is beneficial for 
      improving the adsorption capacity was observed by scanning electron microscopy 
      (SEM). The grafting reaction was confirmed by Fourier-transform infrared (FT-IR) 
      spectroscopy. The adsorbent performance was shown to be better with a lower pH 
      value, a higher adsorbent dosage, or a higher initial Cr(VI) concentration. 
      Moreover, the kinetics study revealed that the adsorption behavior followed a 
      pseudo-second-order model. The isotherm results showed that the adsorption data 
      could be well-fitted by the Langmuir, Freundlich, or Temkin models. Moreover, 
      HBP-g-BC could maintain 74.4% of the initial removal rate even after five cycles 
      of regeneration. Thus, the high potential of HBP-g-BC as a bio-adsorbent for 
      heavy metal removal has been demonstrated.
