Abstract Fe-Si-B amorphous zero-valent iron has attracted wide attention because of its efficient remediation of heavy metals and dye wastewater. In this paper, the remediation effect of amorphous zero-valent iron powder (Fe78Si9B13AP) on Ni contaminated soil was investigated. Results show that the immobilization efficiency of nickel in soil by Fe78Si9B13AP with low iron content is higher than that by ZVI. The apparent activation energies of the reactions of Fe78Si9B13AP with Ni2+ ions is 25.31 kJ/mol. After continuing the reaction for 7 days, Ni2+ ions is mainly transformed into monoplasmatic nickel (Ni0) and nickel combined with iron (hydroxide) oxides. Microstructure More >
