  • What are cross-linked starch and starch-G-polyacrylamide materials?
  • Cross-linked potato starch (StMBA) and starch-g-polyacrylamide materials with a high content of natural polymer from 60 to 90 wt.% (St60–St90) were synthesized by double chemical-chemical modification (grafting and cross-linking). Eco-friendly starch absorbents were tested for removal of Cu 2+ and Fe 3+ from aqueous solutions.
  • Is starch G polyacrylamide a good flocculant?
  • Among those products, starch- g -polyacrylamide copolymer showed good flocculation ability and less monomer toxic after degradation. Cationic starch derivatives with positively charged groups (such as amino, imino, ammonium, etc.) have been studied as effective flocculants over a wide range of pH in wastewater treatment for many years.
  • What is the optimum molecular weight of polyamine-modified starch flocculant?
  • The influence of substrate ratio and molecular weight of cationic polymer on flocculation was investigated and the optimum molecular weight was about 4000. Polyamine-modified starch flocculant was prepared by etherification reaction of cationic polyamine polymer and corn starch.
  • Does starch-G-poly (acrylamide) molecular structure affect sizing properties?
  • The effect of starch-g-poly (acrylamide) (S-g-PAM) molecular structure on sizing properties has been investigated. S-g-PAMs were synthesized with the catalysis of horseradish peroxidase (HRP) and Fourier transform infrared (FT-IR) confirmed the acrylamide (AM) units had been successfully grafted on starch chains.
