“…Since the electro-negativity of Pb(II) is more significant than Cu(II) and Zn(II), the sorption of Pb by soil is preferable. Lead has a more excellent softness value ((Pb(3.58) > Cu (2.89) > Zn (2.34)), which determines the sequence of metal affinity or selectivity of soil components with the formation of covalent bonds 62 – 64 . The interaction of metal cations with the solvent (hydrolysis) also plays a role in their interaction with the adsorbent 64 .…”

“…It was reported that the ability of HM uptake by biochar obtained during the hydrothermal carbonization of peanut hulls changes in the order: Pb(II) > Cu(II) > Cd(II) > Ni(II) 16 . This is mainly due to the differences in hydrolyzability, electro-negativity, and «bond softness» according to Misono et al 60 )), which determines the sequence of metal affinity or selectivity of soil components with the formation of covalent bonds [62][63][64] .

For effective soil remediation, it is vital to apply environmentally friendly and cost-effective technologies following the notion of green sustainable development. In the context of recycling waste and preserving nutrients in the soil, biochar production and utilization have become widespread. There is an urgent need to develop high-efficiency biochar-based sorbents for pollution removal from soil. This research examined the efficacy of soil remediation using biochar made from three distinct sources: wood, and agricultural residues (sunflower and rice husks). The generated biochars were characterized by SEM/SCEM, XRF, XRD, FTIR, BET Specific Surface Area, and elemental compositions. The presence of hydroxyl and phenolic functional groups and esters in wood, sunflower and rice husk biochar were noted. The total volume of pores was in the following descending order: rice husk > wood > sunflower husk. However, wood biochar had more thermally stable, heterogeneous, irregular-shaped pores than other samples. Adsorption of soil-heavy metals into biochars differed depending on the type of adsorbent, according to data derived from distribution coefficients, sorption degree, Freundlich, and Langmuir adsorption models. The input of biochars to Calcaric Fluvic Arenosol increased its adsorption ability under contamination by Cu(II), Zn(II), and Pb(II) in the following order: wood > rice husk > sunflower husk. The addition of sunflower husk, wood, and rice husk biochar to the soil led to an increase in the removal efficiency of metals in all cases (more than 77%). The increase in the percentage adsorption of Cu and Pb was 9–19%, of Zn was 11–21%. The present results indicated that all biochars functioned well as an absorbent for removing heavy metals from soils. The tailor-made surface chemistry properties and the high sorption efficiency of the biochar from sunflower and rice husks could potentially be used for soil remediation.

“…The indicator kriging mapped the areas in which soil contamination exceeds the contamination index Zc groups according to the degree of contamination risk. Bauer et al (2021) applied XAFS and XRD methods for describing the Cu and Zn adsorption characteristics in hydromorphic soils in southern Russia. The sorption processes described with the Langmuir model suggest that Arenosols are more vulnerable to heavy metal input compared to Fluvisols.…”

“…Using XAFS, scientific teams can monitor the samples' redox potential, evaluate the oxidation state of metal pollutants, and examine the local atomic structure of soil and ore components. Similar to the other methods mentioned, XAFS functions best when used in conjugation with other methods of physicochemical analysis (Manceau et al, 2004;Bauer et al, 2022). However, the technique's applicability is restricted by the heterogeneity and polydispersity of soil samples.…”

Analytical techniques for elemental analysis in the soil-plant system have significance importance, especially emerging techniques such as synchrotron radiation (SR). Improved techniques allow samples to be examined in a non-invasive manner at high speed and resolution, resulting in better sample data. By applying various analytical techniques based on SR, it is possible to gather different information about the structure of the studied samples. In mining ecology, such techniques are widely used in assessing heavy metal-polluted sites, i.e., overburden dumps and areas around operating and mothballed mines. The present review elaborated insights into different analytical techniques for applying SR in plant-soil samples. The review also compared traditional research techniques with SR-based emerging and improved techniques. The need to use SR techniques for the complex diagnostics of sample structures to study their elemental and phase composition is substantiated. Using an integrated approach with SR, we can study the dynamics and speciation of HMs with carrier phases and uncover the mechanisms underlying the interactions between the adsorption centers of minerals, organic components, and heavy metals. It also improves the efficiency and accuracy of analysis and broadens the range of information obtained, which could lead to a more precise analysis of samples.
