  • What are polyacrylamide based flocculants?
  • Polyacrylamide-based flocculants constitute the most important group of water-soluble polymers commercially applied in harvesting freshwater and marine microalgae from their suspensions. This is primarily due to the high reactivity, hydrophilic nature and relatively low costs associated with their monomer acrylamide .
  • 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]
  • 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.
  • Are polyacrylamide flocculants toxic?
  • While most polyacrylamide flocculants are stable and non-toxic, some may leave behind acrylamide residues that are anticipated to be neurotoxic, potentially carcinogenic and generally exhibit high toxicity towards aquatic life .
