NOVELTY - Preparing acrylic acid cross-linked copolymerized guar gum/graphene oxide gel adsorbent involves adding graphene oxide to certain amount of mixed acid solvent, sonicating for period of time, cleaning and centrifuging, placing in oven for drying at certain temperature and configuring certain concentration of graphene oxide solution; dissolving guar gum in certain amount of solvent under continuous stirring at certain temperature, then adding graphene oxide solution and continue stirring for period of time, then adding acrylic acid (AA) and initiator, continue stirring at temperature for certain period of time; adding sodium hydroxide, N,N-methylene bisacrylamide and sodium lauryl sulfate to mixing system and continue to stir for certain period of time, then placed in oven and heating at certain temperature, and after linking reaction for certain period of time, then cleaned, and dried at certain temperature to obtain acrylic acid cross-linked copolymer guar gum/graphene oxide gel. USE - Method for preparing acrylic acid cross-linked copolymerized guar gum/graphene oxide gel adsorbent. ADVANTAGE - The method enables to provide solid shape adsorbent, improves solid-liquid separation capacity after adsorption, reduces subsequent operation and treatment process and introduces carboxylic acid group which helps to improve hydrophilicity and adsorption capacity for dyes at same time.
