Activated carbon nanoparticles, barley, Cadmium pollution, Bio-adsorbents


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