Abstract
In this study, BaFe2O4–activated clay nanocomposites were successfully
synthesized via mechanosynthesis technique. Structural analysis of
the products confirmed the nanoscale formation of nanocomposites.
This study focused on adsorption of hydrogen sulfide (H2S) which is
a poisonous gas and can be released from sewage sludge. In the past
years, a growing attention in the usage of adsorptive desulfurization in
industrial applications has been observed due to its many benefits such
as low cost. Nanocomposites were characterized by scanning electron
microscopy (SEM), energy dispersive X-ray (EDS) analysis, Fourier
transform infrared (FTIR), X-ray powder diffraction (XRD). Results
showed different loading of barium ferrite in nanocomposite is important
for adsorption rate. Furthermore, adsorption rate of hydrogen sulfide was
improved by increasing BaFe2O4- activated clay concentration which was
confirmed by statistical results. The highest average of removal efficiency
was 92.79±0.90 in the concentration of 300 g.L-1and loading 6%. We
could recycle BaFe2O4–activated clay nanocomposite, 3 times without a
significant decrease in activity.
