The objective of this work was to investigate the decontamination of a model landfill leachate by simultaneous separation of heavy metals from alkaline earth metals and iron in order to obtain a leachate that can be led back to the landfill. Reactive extraction as a separation process offers the possibility of selectively separating cations, that is, of separating toxic components from less problematic ones, and also includes the possibility of electrolysis and further processes to obtain the desired metals.
