Removal of Brilliant-Green Dye Using Carbon-Loaded Zinc Oxide Nanoparticles: A Comparative Isotherm Study
Adsorption is a phase transfer process extensively utilized for removing substances from fluid phases (either gases or liquids) to the solid phase, also known as the adsorbent particle. This natural method is observable in various environmental compartments. In water or effluent treatments, a solid...

| description | Adsorption is a phase transfer process extensively utilized for removing substances from fluid phases (either gases or liquids) to the solid phase, also known as the adsorbent particle. This natural method is observable in various environmental compartments. In water or effluent treatments, a solid interacts with a pollutant, such as a dye. The pollutant is termed the adsorbate, and the solid is the adsorbent. This technique has been proven efficient in removing a broad range of contaminants. This study investigates the use of the adsorption technique to eliminate brilliant-green dye from aqueous solutions, employing different adsorbent materials like AC, CNT, ZnO, and ZnO/AC prepared through the hydrothermal method. The compositions of these composites were elucidated using analytical techniques such as FTIR, EDX, and FE-SEM. The study also compares the efficiency of different carbon sources in removing brilliant-green dye, namely, activated carbon (AC), carbon nanotubes (CNTs), zinc oxide (ZnO), and AC/ZnO nanocomposites as adsorbents. The removal efficiency (E%) for BG dye followed the order: CNT > ZnO/AC > AC > ZnO. Additionally, a comparison was made between sonication and a shaker water bath for different carbon sources in removing brilliant-green dye. The shaker water bath demonstrated an efficiency range of 90.122% to 42.812%, while sonication showed 90.011% to 32.012%. The adsorption data aligned with the Freundlich isotherm model. |
