Abstract

This study included the preparation and characterization of carbon nanoparticles prepared from environmentally friendly plant sources, namely a mixture of walnut shells and date kernels, as diagnosed by atomic force microscopy (AFM) and transmission electron microscopy (TEM), as the results showed that the prepared carbon particles were within nano-size and square in shape, in addition to studying and determining the wavelength of the dye [EBT] under study. It was 516 nm, and the adsorption efficiency of the nano-carbon prepared for the dye was 95.0%. With an ideal weight of 0.5 g, it was found that the equilibrium time was 20 minutes. The results showed that the adsorption efficiency increased at the natural pH of the dye. The thermodynamic functions of adsorption were also calculated, and it was found that the adsorption system was automatic (ΔGº) and less random (ΔSᵒ) and exothermic ((∆Hº) at temperature (Tk).
