Özet

In this research, MnO2-GO nanocomposite is synthesized under laboratory conditions and it was to take the Malachite Green (MG) dye-from a raw paper industry wastewater. XRD, HR-TEM and FT-IR analysis showed that the produced MnO2 peak located belong to GO and this is attributed to 2 theta=10 au. FT-IR analysis showed that MnO2-GO nanocomposite has some oxygenated and stretching groups like Mn-O, O-H, C=C, C-O-C. The maximum MG adsorption capacity was detected to be 90% with an at optimum adsorption time of 18 min at a MG dye concentration of 18 mg/L with 10 mg/L MnO2-GO nanocomposite. The maximum sorption loading was recorded as 3.8 mg/g at 18 mg/L Malachite Green dose at a temperature of 21 degrees C. Among the kinetic applied to the adsorption data it was found that the MG was adsorbed to MnO2-GO nanoparticle according to Intra-particle diffusion model with q=11.01 mg/g, and k(1)=0.085 1/min.
