Abstract

In this study, Vachellia nilotica was utilized to formulate initiated activated carbon (AC), which was then incubated with potassium hydroxide at 600°C for two hours. FTIR, TGA/DTA, and SEM/EDAX were used to characterize the functional groups, surface shape, thermal stability, and elemental identification of the activated carbon. Furthermore, the efficacy of the AC remediation was evaluated using dye (Congo Red) under different conditions, such as pH and dose, and the maximum amount of Congo Red that the adsorptive material could absorb was measured using the Langmuir and Freundlich adsorption isotherm principles. The Langmuir isotherm model fits the maximal dye adsorption capacity well, which was attained at 24.35 g/L. In order to improve (raise) the water’s potability level, the research’s findings suggest that Vachellia nilotica may be used as a cost-effective and capable raw material to create initiated carbon for wastewater treatment.
