Abstract

The study examined the adsorption of methylene blue from an aqueous solution using activated carbon-loaded copper nanocomposites (Cu@AC). The activated carbon was obtained from Acacia Crassicarpa bark. The Cu@AC were synthesized using a thermal treatment, with a focus on minimizing the time required and assuring an environmentally-friendly and sustainable approach. The Cu@AC nanocomposites underwent characterization using XRD, SEM, EDX, and FTIR techniques. Subsequently, they were subjected to tests to determine their adsorptionisotherm and the impact of experimental factors on the removal of RhB from an aqueous solution. Monolayer adsorption of Rhodamine B was determined to be favorable, with a maximum adsorption capacity of 47.85 mg/g at a temperature of 298 K. The results demonstrate that the Cu@AC nanocomposite may be effectively used as a highly efficient adsorbent for large-scale wastewater treatment.
