Polysaccharide-based beads and water purification: A review.

Polysaccharide-based beads have attracted considerable interest as efficient materials for remediation of water contamination because of their excellent adsorption capability and eco-friendly properties. This review analyzes recent progress in developing biopolymeric magnetic hydrogels deduced from polysaccharides like cellulose, starch, alginate, chitosan, lignin, pectin, guar gum, carrageenan, and agar. It emphasizes their use in eliminating heavy metals, dyes, oil, and antibiotics from polluted water.

Flexible high electrochemical collagen/lignin composite hydrogel for sensing and supercapacitor applications.

Synthesis of polymer-based highly conductive hydrogels from natural and renewable sources with robust mechanical performances in flexible electronics remains a great challenge. In this research, a dynamic redox system is designed by using collagen (CL), sulfonate lignin (SL), acrylic acid (AA), and Al to synthesize CL/PAA/SL/Al hydrogels. The formation of effective complexes of Al with the abundant functional groups of CL, SL and PAA, the prepared hydrogel delivers various specific properties, for example, excellent ionic conductivity (4.
