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 FTIR
analysis showed that the produced MnO2 peak
located belong to GO and this is attributed to 2Ө=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
ºC. 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 k1=0.085 1/min.
