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,
