Investigators used the commercial iron product Nanofer 25s in a study to evaluate the effectiveness of NZVI treatment for the decontamination of marine sediments containing heavy metals (Al, As, B, Ba, Co, Cu, and Ni). Experimental activities were conducted on sieved sediment with a particle size < 5 mm. The NZVI treatments included 2, 3, and 4 g of product per kg of sediment (low dosage) and 5, 10, and 20 g of product per kg of sediment (high dosage). The optimal amount of NZVI for sediment reclamation was selected as 4% and 5% in the case of low and high dosages, respectively. Results indicated that NZVI was better suited to the removal of specific elements rather than to application for generalized contamination. http://www.aidic.it/cet/17/60/024.pdf
