Özet
In this study, it was aimed to modify the coal sample (CS) with oxygen plasma treatment for the first time. The plasma treatment process on the CS was evaluated by malachite green (MG) dye adsorption. The oxygen plasma treatment on the surface of CS was analysed by X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and nitrogen adsorption. It was found from the analysis results that the number of oxygenated groups on the CS surface increased. The mechanism for oxygen plasma on the CS was evaluated. It was concluded that oxygen plasma treatment was suitable for surface modification of the CS and that the adsorbent obtained was effective for MG adsorption.
