  • 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 native starch a hydrophilic polymer?
  • It is a hydrophilic polymer containing a multitude of hydroxyl groups with a reactivity comparable to alcohols. Native starch shows a considerably low absorption ability and cannot be used directly as an absorbent. To improve absorption, it is necessary to modify native starch by introducing active groups with chelating and sorption abilities.
  • What is stmba and G-polyacrylamide?
  • Author to whom correspondence should be addressed. 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).
  • How are cross-linked acrylamide starch copolymers synthesized?
  • The cross-linked acrylamide starch copolymers were synthesized by free radical initiated polymerization of potato starch (St, 2.28 g) with acrylamide (AM content from 10 to 40 wt.% on the starch weight).
