  • 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.
  • How is polyamine-modified starch flocculant prepared?
  • Polyamine-modified starch flocculant was prepared by etherification reaction of cationic polyamine polymer and corn starch. The influence of substitution degree (DS) of starch on flocculation was investigated and the maximum DS was 0.18.
  • 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.
