Abstract
Iron oxide nanocomposite (Fe2O3-CuO) has been prepared and used as an adsorbent in this study
to remove methylene blue. The process to synthesize the samples is based on two methods which
are solid state reaction and sol-gel method. Two sample prepared, SS02 (solid state) and SG02 (sol gel) was further characterized and the micropore surface area and total pore volume is determined.
For SS02, the micropore surface area and total pore volume are 5.9476 m
2
/g and 0.003061 cm3
/g
respectively. Meanwhile for SG02, the micropore surface area and total pore volume are 11.0242
m
2
/g and 0.005762 cm3
/g respectively. The elemental composition of the samples is obtained by
XRD to check the presence of element Fe2O3 and CuO and it shows almost identical pattern for
both adsorbent that had been synthesized by different method. The effect of initial dye
concentration (25-300mg/L), contact time (0-24 hours) and solution temperature (30-60⁰C) were also
evaluated through. However, the adsorption process is not obtained in this study because iron oxide
nanocomposite is not suitable for adsorbent in methylene blue removal.
