Comparative studies of sorption of phenolic compounds onto carbon-encapsulated iron nanoparticles, carbon nanotubes and activated carbon

- Sorption capacity changes in the following order: AC > CNTs > CEINs.
- 4-Chlorophenol has the highest adsorption affinity.
- Sorption performance of CEINs increases 7 times after surface activation.
- Sorption kinetics rate of CEINs and CNTs is 100 times higher in comparison to AC.
- CEINs have the highest regeneration yield.
