Abstract
, the Langmuir isotherm provided an optimal fit to the experimental data, proving CLCTB's high adsorption efficiency for Cd. The process was confirmed to be both spontaneous and exothermic through thermodynamic analysis. Additionally, the beads exhibited excellent reusability over six adsorption-desorption cycles, maintaining high performance, which highlights their potential for practical application in water treatment. This study presents CLCTB as a promising, sustainable, and eco-friendly adsorbent for the efficient removal of Cd from contaminated water.
