Abstract :
In the current work, the synthesis and modification of graphene oxide with Nickel Hexa Ferrocyanide (NiHCF) nanoparticles has been reported. The obtained product was characterized and used as an adsorbent to remove Cesium (Cs) ions from a simulated solution. Studying the Cs uptake in various pHs indicated that it reaches about 99% at a pH range of 6-7. The results cleared that the maximum adsorption for Cs was 240 mgg-1. Equilibrium modeling studies suggest that the data are reasonably and relatively fitted well to the Langmuir adsorption isotherm. Kinetic studies show that the sorption process is fairly rapid and equilibrium is achieved at an initial 30 min of contact time, as well the kinetic data are fitted well to the pseudo-second-order rate mode.
