Preparation and characterization of a new bis-uracil chitosan-based hydrogel as efficient adsorbent for removal of anionic congo red dye

HIGHLIGHTS

  • who: Rana A. Alharbi and collaborators from the Department of Chemistry, College of Science, Qassim University, Buraidah, Saudi Arabia have published the research: Preparation and Characterization of a New Bis-Uracil Chitosan-Based Hydrogel as Efficient Adsorbent for Removal of Anionic Congo Red Dye, in the Journal: Polymers 2023, 1529 of /2023/
  • what: Chitosan was chemically modified by incorporating 2Clph-BU linkages between its chains.
  • how: The thermodynamic results showed that the adsorption process was endothermic because of the positive value of enthalpy (43.70 kJ mol-1 ).
