Title: New magnetic-enhanced adsorption process for wastewater treatment

Abstract

Radioactive and nonradioactive metal ion and particulate species in aqueous solutions present a formidable treatment problem for the nuclear and commercial industries. An economical and highly effective system for the treatment of wastewater containing these metal species is presented that uses a new magnetic enhanced adsorption technique. The process employs low-cost magnetite (FeO{center_dot}Fe{sub 2}O{sub 3}) supported on various organic and inorganic support media, and an external magnetic field to couple the inherent sorption properties of the magnetite with a high gradient magnetic separation technique. This combination of sorption techniques offers several advantages over current filtration and ion exchange systems and removes a variety of heavy metals and radioactive species. Filtration systems do not remove ionic species, and ion exchange systems can be plugged by particulate matter, which may limit the amount of exchange sites able to be accessed.
