“…The surface retention mechanism complements the mechanisms described earlier and contributes to MO-CAg effective immobilization for metals. 26,36,37 Based on the DFT calculations, the shorter bond length between MO-CAg and oxygen, or other oxygen-containing functional groups, exhibits the possibility of stronger bond formation with Cd(II) and Pb(II) ions. Both Cd(II) and Pb(II) have a low tendency to be hydrolyzed, and this increases the probability of their retention onto MO-CAg rather than onto biochar and CAg.…”

“…The most widely used remediation methods are usually based on two main methodologies, in situ or ex situ remediation [3,4]. Both in situ and on site remediation could be performed by different methods such as solidification and stabilization, oxidation, soil vapor extraction, bioremediation, or nanoremediation [4][5][6][7]. On one hand, in situ soil treatment is a method in which the contaminated soil is treated without removing it.…”

Zero-valent iron has been reported as a successful remediation agent for environmental issues, being extensively used in soil and groundwater remediation. The use of zero-valent nanoparticles have been arisen as a highly effective method due to the high specific surface area of zero-valent nanoparticles. Then, the development of nanosized materials in general, and the improvement of the properties of the nano-iron in particular, has facilitated their application in remediation technologies. As the result, highly efficient and versatile nanomaterials have been obtained. Among the possible nanoparticle systems, the reactivity and availability of zero-valent iron nanoparticles (NZVI) have achieved very interesting and promising results make them particularly attractive for the remediation of subsurface contaminants. In fact, a large number of laboratory and pilot studies have reported the high effectiveness of these NZVI-based technologies for the remediation of groundwater and contaminated soils. Although the results are often based on a limited contaminant target, there is a large gap between the amount of contaminants tested with NZVI at the laboratory level and those remediated at the pilot and field level. In this review, the main zero-valent iron nanoparticles and their remediation capacity are summarized, in addition to the pilot and land scale studies reported until date for each kind of nanomaterials.
