“…SO 4 c− and c OH were the dominant reactive species in the TA-Fe(II)-PS system, attacking TCE to generate non-toxic products such as CO 2 , Cl − , and H 2 O. 50,51 As shown in Fig. S2, † the Cl − concentrations gradually increased, indicating the organochlorine was converted into Cl − .…”

“…Biochar is not only an effective material for environmental remediation but can also be used in other fields [51,52]. In environmental management, biochar can be used for several purposes, as shown in Figure 1, including the following: the improvement of soil quality [53,54], greenhouse emission reduction (mainly CO 2 ), climate change mitigation [55,56], waste and heavy metals management [57][58][59][60][61][62], and as adsorbent material for the removal of heavy metals from contaminated water [63][64][65][66][67]. The biochar applications shown in Figure 1 are in addition to its well-known use for modifying and improving the chemical-physical characteristics of soils, as reported in [68][69][70][71][72].…”

The purpose of this manuscript is to present a review of laboratory experiments (including methodology and results) that use biochar, a specific carbon obtained by a pyrolysis process from different feedstocks, as an alternative material for heavy metal adsorption from groundwater. In recent years, many studies have been conducted regarding the application of innovative materials to water decontamination to develop a more sustainable approach to remediation processes. The use of biochar for groundwater remediation has particularly attracted the interest of researchers because it permits the reuse of materials that would be otherwise disposed of, in accordance with circular economy, and reduces the generation of greenhouse gases if compared to the use of virgin materials. A review of the different approaches and results reported in the current literature could be useful because when applying remediation technologies at the field scale, a preliminary phase in which the suitability of the adsorbent is evaluated at the lab scale is often necessary. This paper is therefore organised with a short description of the involved metals and of the biochar production and composition. A comprehensive analysis of the current knowledge related to the use of biochar in groundwater remediation at the laboratory scale to obtain the characteristic parameters of the process that are necessary for the upscaling of the technology at the field scale is also presented. An overview of the results achieved using different experimental conditions, such as the chemical properties and dosage of biochar as well as heavy metal concentrations with their different values of pH, is reported. At the end, numerical studies useful for the interpretation of the experiment results are introduced.
