Electroerosion Coagulation and Dispersion for Complex Water Purification, Waste Recycling and Manufacturing of Metals, Oxides, and Alloys Nanopowders

The application of electroerosion coagulation together with in-situ manufactured polyvalent powdered aluminium oxides and iron oxides allowed efficient water purification from heavy metal ions and radioactive alkali ions (Fe, Cr, Cu, Mo, Zn, Co, Ni, Cd, Mn, As, Sn, Pb, Al, Ba, Cs and Sr) as well as from organic contaminations (from the liquid waste landfills, in particular) [1]. The method of electroerosion dispersion is very effective for production of nanopowders (5-500 nm) of metals, oxides, nitrides and carbides, as well as for recycling of any conductive materials such as cemented carbides, alloys of heavy metals, any metallic granules or chips, cans, etc [2]. The iron magnetic nanoparticles produced by electroerosion dispersion have considerable interest in many fields of research and application due to their attractive properties. They have high potential for applications in the field of biomedical sciences (diagnostics and therapy), ferrofluids, catalysis, colored pigments, high-density magnetic recording, printer toners, Li-ion batteries, wastewater treatment and absorption of electromagnetic waves.
