Preparation and recycled simultaneous adsorption of methylene blue and Cu2+ co-pollutants over carbon layer encapsulated Fe3O4 /graphene oxide nanocomposites rich in amino and thiol groups

Fenghua Chen et al.

Summary: The Fe3O4@C/GO nanocomposites exhibited efficient adsorption capacities for MB and Cu2+, with the pseudo-second order rate model best simulating the kinetic adsorption process and the Langmuir adsorption isotherm model providing a better fit for the adsorption data. The presence of MB in a binary system had a suppression effect on the binding of Cu2+ ions during simultaneous adsorption, but had almost negligible impact on the adsorption capacity of MB when preloaded with Cu2+ ions.

Dark-Fenton oxidative degradation of methylene blue and acid blue 29 dyes using sulfuric acid-activated slag of the steel-making process

Norhaslinda Nasuha et al.

Summary: The study showed that the oxidative degradation of dye effluents using sulfuric acid-activated electric arc furnace steel slag under dark-Fenton process conditions was effective, with the predominant crystalline ferrous ions on the catalyst promoting the generation of center dot OH radicals for oxidation. Experimental data and Langmuir-Hinshelwood model application validated the dominant role of surface reaction, supported by the activation energy. The S-EAF catalyst sustained oxidative degradation for seven cycles with minor leaching of irons(Fe).
