Management of 137Cs in electric arc furnace dust by solid-liquid extraction and treatment of contaminated wastewater using co-precipitation

Case Studies in Chemical and Environmental Engineering, 2023
Efficient decontamination of 137Cs in electric arc furnace dust (EAFD) was carried out using a solid-liquid extraction method and then the obtained wastewater contaminated with 137Cs was treated by a co-precipitation. The influences of pH, stirring time,

Electrochemical Properties of NdCl₃ and CeCl₃ in Molten LiCl-KCl Eutectic Salt

Applied Sciences, 2020
NdCl3 and CeCl3 are characterized by the very close proximity of their standard reduction potentials. Thus, they represent the most challenging salt mixtures with respect to decoupling electrochemical responses and calculating concentrations.
