Hybrid Material Based on an Amorphous-Carbon Matrix and ZnO/Zn for the Solar Photocatalytic Degradation of Basic Blue 41

Molecules, 2019
Innovative composites based on an amorphous-carbon matrix containing a second phase ZnO oxide and/or highly dispersed Zn metallic were synthesized via a modified Pechini route, in which a partial pyrolysis method was reached. Studies of adsorption in the

Recovery of Cs-137 from electric arc furnace dust by lixiviation

Case Studies in Chemical and Environmental Engineering, 2022
An orphan radioactive source of Cs-137 was inadvertently melted in an electric arc furnace, generating large volumes of electric arc furnace dusts contaminated with Cs-137 (137Cs-EAFD). This work proposes the Cs-137 recovery from 137Cs-EAFD by applying a

Removal efficiency of 137Cs from radioactively contaminated electric arc furnace dust using different solvents

Case Studies in Chemical and Environmental Engineering, 2023
An advertent meltdown of radioactive source during steel smelting generates electric arc furnace dust (EAFD) polluted with 137Cs. The removal efficiency of 137Cs from EAFD was assessed by the lixiviation method using different solvents and at various ...
