“…Vitrification, also known as liquefied glass utilization, is a solidification/ stabilization process that utilizes a formidable energy source to dissolve earthen or other soil components at incredibly great temperatures (1,600-2,000°C), removing organic and immobilizing most inorganics pollutants by heating (Lin et al, 2021). The bulk of chemicals subsequently found in the earth are volatilized during this phase, whereas the remnants are processed into crystalline products, solid glass, and chemically inert materials (Navia et al, 2005).…”

Soil pollution of numerous inorganic and organic chemicals has resulted to the destruction of vast amounts of arable and urban land around the world. Toxic pollutants pose a serious health danger to individuals as well as other biological processes. Dispersed literature is used to scientifically examine the numerous physical and anthropogenic causes and probable risks to determine the remediation solutions for a variety of toxins and heavy metals. This review discusses the remediation approaches such as phytoremediation as well as the chemical strategies. Chemical remediation methods like soil cleaning or verification are comparatively extensive and environmentally harmful, making them unsuitable for big-scale soil remediation operations. Phytoremediation, on the other hand, has arisen as an environmentally sustainable and viable technique for restoring the polluted soils, but relatively little attempts have been made to demonstrate this technique in the region. Heavy metal-polluted soil remediation is needed to decrease the related dangers, increase the land requirements for agricultural cultivation, improve food security, as well as reduce land tenure issues caused by changing land-use patterns.

“…9 Adsorption has gained extensive usage among these methods not only for its versatile operation but also for its high capacity to adsorb. Various adsorbents, such as clay, 10 cotton fiber, 11 chitosan, 12 and zeolite, 13 have been developed for cobalt removal. However, these materials still encounter problems such as poor capacity of adsorption or unstable structure.…”

In this study, researchers developed a novel composite material called NH 2 -MIL-53-Al/PAN, which consists of metal−organic frameworks (MOFs) grown on electrospun PAN nanofibers (NFs). The successful formation of the composite was confirmed by X-ray diffraction (XRD) and Fourier transform infrared (FTIR), and the hydrophilicity of NH 2 -MIL-53-Al/PAN was demonstrated by the water contact angle (WCA). Batch experiments were conducted to investigate the adsorption performance of Co(II) under different conditions. The maximum adsorption capacity reached 58.72 mg/g, and almost 95% of the adsorption was achieved within the first 6 h. The adsorption process was found to be spontaneous and endothermic and followed the pseudo-second-order kinetics and Langmuir models. Chemisorption and molecular layer adsorption are the main mechanisms of adsorption, and X-ray photoelectron spectroscopy (XPS) analysis further reveals that the interaction between the adsorbent and cobalt is a coordination interaction. In this study, NH 2 -MIL-53-Al was grown in situ on PAN to ensure effective loading of MOFs and prevent agglomeration during the NF mixing process. This approach successfully addressed the challenge of exposing active sites within the embedded MOF crystals. Additionally, it overcame the difficulty of recycling traditional MOF adsorbents. As a result, the exceptional performance of MOF NFs offers a promising solution for the efficient removal of cobalt-containing wastewater.

“…Due to its high solubility, Tl(I) adsorption plays a crucial role in reducing its mobility and bioavailability, while precipitation reactions are less significant [18][19][20]. The adsorption of Tl(I) by soils is influenced by the contents of clay, organic matter, and oxides of Al, Fe, and Mn [19,[21][22][23][24][25]. Specifically, clay minerals can adsorb Tl + ions to a greater extent due to the high affinity of their cation-exchange sites toward Tl + ions [18,24,25].…”

This study investigated the uptake of thallium (Tl) by rice seedlings grown in different soils with varying physiochemical properties and Tl levels to elucidate the key factors governing soil Tl availability and accumulation in rice plants. The bioconcentration factors of Tl in rice roots (2.5–25.6) and shoots (1.5–14.7) indicated high soil Tl availability and efficient uptake and translocation of Tl in rice plants, with significant variations across soil types. Growth suppression and visual toxic symptoms, such as stem buckling, yellowish leaf tips, and withering leaf edges, occurred at low soil Tl levels due to high Tl toxicity. The accumulation of Tl by rice plants was influenced by both soil and plant-related factors. Cation exchange reactions primarily influenced the concentration of Tl in soil solution, with potassium ions (K+) acting as competitors for cation exchange sites with Tl+ ions and effective inhibitors of Tl uptake by rice plants. Increasing soil K content may mitigate soil Tl availability in contaminated soils by reducing soil Tl(I) adsorption and plant uptake. This study elucidates the key mechanisms governing soil Tl bioavailability and highlights potential management strategies to reduce Tl accumulation in crops.
