Özet:

 

Sodium dodecyl sulfate (SDS) was chosen to obtain a sandwich type assembly
of SDS and graphene (GR) sheets. The modified (SDS/GR) and unmodified GR were characterized by powder X-ray diffraction (XRD),
high-resolution transmission electron microscopy (HRTEM), Fourier transform infra-red (FTIR) spectroscopy, as well as thermal (TG) 
and TMA analyses. The SDS obviously prompts the dispersion of GR into a typical
wrinkled layered structure. The addition of SDS into GR has lowering the
coefficient of thermal expansion (CTE).  137Cs is the most currently
radioactive isotope generated in the area around the Chernobyl disaster. Cerium is quantitatively concentrated and
separated from Egyptian monazite by leaching the monazite lanthanide oxides
cake. So, SDS/GR was applied to remove Cs(I) and Ce(III) from aqueous solutions
using a batch technique. The factors pH, contact time, temperature, and dosage
were investigated. The
highest adsorption capacity of SDS/GR is found to be 44 and 60 mg g-1for
137Cs(I) and  Ce(III),respectively.
The adsorption of Cs(I) and Ce(III) onto SDS/GR ﬁtted the pseudo-second-order
model. It was found that the adsorption processes have reached their
equilibrium state in about 2h, which is faster than most of carbon-based
adsorbents can do. From the thermodynamic parameters the sorption process was
endothermic and spontaneous in nature.
