Nanoscale zerovalent iron (NZVI) particles have recently become subject of great interest in the field of groundwater remediation for their ability to treat a wide variety of organic and inorganic contaminants. However, the field application of this technology is strongly hindered by the lack of stability of NZVI water suspensions. This study demonstrates that highly concentrated NZVI slurries (15g/L) can be stabilized for more than 10 days adding 6g/L of xanthan gum biopolymer. Stability… CONTINUE READING
