The nanoscale zero-valent iron supported on activated charcoal (nZVI/AC) by the reduction of ferrous sulfate heptahydrate with sodium borohydride was synthesized for uranium(VI) adsorption. The nZVI/AC was characterized using X-ray radiation diffraction and scanning electron microscope. The adsorption kinetics, adsorption isotherms and adsorption thermodynamics were also examined. The adsorption capacity reached 492.6 mg/ g when dosage was 0.5 g/L, initial concentration of uranium(VI) was 250 mg/L, pH was 5, temperature was 35°C and time was 60 min. The experimental results indicated that nZVI/AC possessed many advantages such as simple and economy for preparation, less adsorbent dosage, short balance time, high adsorption ratio and adsorption capacity. The synthesized adsorbent is promising to efficiently treat the uranium-contained wastewater.

“…When the adsorption peaks are compared, it is Binding engrgy, eV clear that the FT-IR spectra of the carbon materials obtained at different temperatures and reaction times are almost the same. Straightforward chemical modification of carbon, such as grafting other chemical groups to the carbon surface, is possible because of these functional groups [24][25][26] .…”

Amorphous nitrogen-containing carbon was successfully prepared by carbonization of furfural in a deep eutectic mixture of urea and choline chloride. Primary amine groups were able to be anchored to the carbon in a one-pot solvothermal carbonization procedure. XPS analysis showed that nitrogen predominantly bound within the solid as well as at the surface. An abundance of functional groups on the surface of the carbon during the carbonization process generated large, graphite-like interlayer spaces. N-doped carbon exhibits reactive surfaces because nitrogen can easily be further modified through the grafting of other chemical groups. The carbon obtained by this innovative approach may be a good matrix for solid phase extraction because of its narrow pore size.
