Abstract:
Due to nZVI effectiveness in the removal of toxic metals as well as low-cost regarding its production, kaolinite, bentonite and carboxymethyl cellulose supported nZVI were chosen for in-situ remediation of river sediment. Small-scale laboratory studies have shown that the percentage of removed metal (Ni, Zn and Pb) ranged up to 80% depending on the nanomaterial used. The metal mobility in sediments was investigated using single extraction, which is proved to be better for quick estimation of metal mobility, and for highly contaminated sites both single and sequential extraction needs to be used. Risk assessment code indicated medium risk for Ni and high risk for Pb and Zn in untreated sediment. In-situ treatment in laboratory proved to be very effective, providing the choice of optimal doses of three different nanomaterials used towards the concentration of toxic metals in the sediment.
