  • What is a polymer flocculant?
  • Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
  • Can polyacrylamide grafted xanthan gum/silica based nanocomposite be used as flocculant?
  • This manuscript illustrates the feasibility of polyacrylamide grafted xanthan gum/silica based nanocomposite toward its potential application as high performance flocculant for treatment of synthetic effluents and mine wastewater.
  • Are synthetic polymers effective flocculants?
  • Synthetic polymers are highly effective flocculants at low dosages but have poor shear stability. In the case of water-soluble polymers, their flocculating effect depends on the size of the random coils (i.e., the radius of gyration), which are the privileged conformation in solution.
  • Are nanocomposite flocculants based on synthetic polymers?
  • Most of the literature presents, however, nanocomposite flocculants based on synthetic polymers [ 230, 231 ]. An example of nanocomposite with using both synthetic and natural polymer is mentioned earlier graft copolymer of polyacrylamide/xanthan gum with silica nanoparticles [ 113, 114]
