Activated Carbon Nanoparticles as Adsorbent to Remove the Cadmium Ion from Aqueous Solution: Thermodynamic Study

Human activities such as fossil fuel burning, car exhaust, mining, agriculture, and the incineration of solid liquid wastes all contribute to water pollution by heavy metals, therefore this poisoning poses a threat living beings. To minimize natural waters, As adsorption process metal in solutions, it is critical identify effective strategies for getting rid these toxins. This study involves characterization synthesis novel activated carbon nanoparticles (AC) from sources (barley) applied an remove cadmium metal. using XRD, SEM was nanoscale size particle-like shape also BET specific surface area nitrogen isotherm nitrogen) 718.01 ) Average pore diameter (16.851(Å)), experimental data, results are best described Freundlich model, which has removal 76.86% with exothermic process.
