Abstract [en]

Svensk Sjömuddring AB (SSM) is a company that can be contracted to remove metals from contaminated soils, specializing in soils from military sites. The soils are generally contaminated with a wide range of metals, with the most prevalent being Cu, Zn and, the biggest problem, Pb. Typical levels range for a few hundred milligrams per kilogram for Cu and Zn to several grams per kilogram for Pb. Acceptable levels, as defined by Swedish regulations lie around 200 mg/kg, depending upon the metal. SSM has a process for removing these metals, using physical processes (magnetic separation, cyclones, screening, etc.), however, these processes cannot cope with the fraction of the soils with particle size less than 0.5 mm. Currently, this fraction of the soil (which can account for around 40% of the soil) must be taken to a landfill site capable of storing toxic materials. Hence, it was the purpose of this work to evaluate chemical and electrochemical methods for removing Cu, Zn and Pb from the fine fraction of contaminated soils.
