Design of a hybrid bio-adsorbent based on Sodium Alginate/Halloysite/Hemp hurd for methylene blue dye removal: kinetic studies and mathematical modeling

Gianluca Viscusi et al.

Summary: This research focuses on designing and fabricating green and sustainable systems for efficient removal of methylene blue from aqueous solutions. Hybrid beads were produced using ionotropic gelation technique with calcium chloride, consisting of a sodium alginate matrix, hemp hurd, and halloysite nanoclay. The adsorption capacity of the composite beads was found to increase with higher HNTs content, with the process mainly characterized by boundary diffusion and intraparticle diffusion. Additionally, diffusion of the dye varied with HNTs content and pH, decreasing from acidic to neutral solutions and then increasing in an alkaline environment.

Jie Gao et al.

Summary: Bio-based adsorbents were developed to remove dye contaminants for sustainable development. Aromatic bio-based tannin was incorporated into pure sodium alginate adsorbent to enhance its adsorption capacity. The Tan/SA composite hydrogel beads showed millimeter-sized beads with enhanced thermal stability. The 40% Tan/SA adsorbents achieved a maximum capacity of 247.2 mg/g at optimal conditions (pH = 12, T = 45 degrees C) with a removal efficiency of 82.4%. The adsorption process was endothermic and showed chemical adsorption, with a removal efficiency exceeding 90% after five cycles.
