In this post, we present a brief overview of our recently published book chapter titled “Methylene Blue Adsorption Utilizing Enhanced Chitosan Beads: A Response Surface Methodology and Artificial Neural Network Study.”
The structural and surface properties of the produced chitosan beads were assessed using XRD and BET analysis. XRD studies confirmed chitosan’s semi-crystalline structure, with distinct broad peaks showing the existence of both amorphous and organised domains. This structural information is critical for determining the stability and binding potential of the created materials. In addition, the BET surface area analysis revealed a higher surface area and pore volume than native chitosan. These benefits are directly related to increased adsorption effectiveness, as a larger surface area affords more active sites for pollutant interaction. The XRD and BET data demonstrate that the created chitosan beads have the structural integrity and textural qualities necessary for long-term adsorption applications in wastewater treatment.
