Abstract In this study, the remediation experiments were performed outdoors in natural conditions. Carboxymethyl cellulose (CMC)-stabilized nanoscale zero-valent iron (CMC-nZVI), biochar (BC) and CMC-stabilized nanoscale zero-valent iron composited with biochar (CMC-nZVI/BC) were synthesized and investigated for their effect on the in situ remediation of hexavalent chromium [Cr(VI)] contaminated soil and the concentration of available iron was tested after the remediation, compared with the untreated soil. The results of toxicity characteristic leaching procedure (TCLP) test showed that CMC-nZVI and CMC-nZVI/BC used as remediation materials could obviously improve the remediation rate of Cr contaminated soil and when the ratio of CMC-nZVI to Fe0 was 2.5 g/Kg, the leachability of Cr(VI) and Crtotal can be reduced by 100% and 95.8% simultaneously. Moreover, sequential extraction procedure (SEP) showed that most exchangeable Cr converted to carbonate-bound and Fe-Mn oxides-bound, reducing the availability and leachability of Cr in the soil.

Preliminary Study

In this study, nanoscale zero-valent iron (nZVI) and nZVI/reduced graphene oxide (RGO-nZVI) nanocomposites were prepared, and the effect of nZVI, RGO-nZVI and graphene oxide (GO) on Indian marigold were examined by pot trials with contaminated soils amended with nanomaterials. The observed results show that 0.05% nZVI and 0.05% RGO-nZVI can wilt the Indian marigold, and they exhibit significant in situ mobility in fluvo-aquic soils. In this paper, the feasibility of improving the phytoremediation efficiency of contaminated soils by amending with nanomaterials is also discussed.
