CONTEXT

Industrial effluents usually comprises highly toxic dissolved metals (Ag, Au, Cd, Cu, Hg, Ni, Zn, Pd et Pb)
making them hazardous for the environment. Treating such effluents is a major issue especially that more and more regulatory measures are implementated to avoid any pollution of the environnement. Therefore numerous chemical processes exist to decontaminate these effluents but none of them are actually fully efficient and most of them use expensive reactants. If we add the fact that pollutant such as noble metals can have a high value afterward, there definitely exists a demand for a fully efficient inexpensive process.
