“…All these organic functional groups can provide strong support to the surface modification of biochar. In addition, the surface functional groups of the modified Mn/Mg@MV composite biochar changed significantly but still retained the aromatic functional groups C=C (~1420 cm −1 ), C=O (~1631 cm −1 ), and C-O (~1048 cm −1 ) [ 46 ]. It is well known that aromatic structures act as π-electron donors and, in most cases, achieve the removal of target organic pollutants via π-π electron donor–acceptor (EDA) interactions [ 47 ] and are synergistic.…”

Transition metals and their oxide compounds exhibit excellent chemical reactivity; however, their easy agglomeration and high cost limit their catalysis applications. In this study, an interpolation structure of a Myriophyllum verticillatum L. biochar-supported Mn/Mg composite (Mn/Mg@MV) was prepared to degrade triphenyl phosphate (TPhP) from wastewater through the activating periodate (PI) process. Interestingly, the Mn/Mg@MV composite showed strong radical self-producing capacities. The Mn/Mg@MV system degraded 93.34% TPhP (pH 5, 10 μM) within 150 min. The experimental results confirmed that the predominant role of IO3· and the auxiliary ·OH jointly contributed to the TPhP degradation. In addition, the TPhP pollutants were degraded to various intermediates and subsequent Mg mineral phase mineralization via mechanisms like interfacial processes and radical oxidation. DFT theoretical calculations further indicated that the synergy between Mn and Mg induced the charge transfer of the carbon-based surface, leading to the formation of an ·OH radical-enriched surface and enhancing the multivariate interface process of ·OH, IO3, and Mn(VII) to TPhP degradation, resulting in the further formation of Mg PO4 mineralization.

“…Previous works have demonstrated that biochar derived from sugarcane bagasse is an important source of organic matter and a valuable amendment to ameliorate the chemical, physical and biological fertility of soils with low organic matter content (Azeem et al 2019;Bento et al 2019;Zafar-ul-Hye et al 2020;Rahman et al 2021). Sugarcane bagasse biochar is characterized by high specific surface area, abundant micropores and high surface functional groups (Moradi-Choghamarani et al 2019), which can sorb and immobilize heavy metal ions (Ding et al 2014;Sarker et al 2017;Bashir et al 2018;Zahedifar and Moosavi 2020). Several studies have suggested that sugarcane bagasse-derived biochar could be used as a potential sorbent for metal removal and immobilization to remediate metal-contaminated soils, and to decrease metal toxicity to the soil microbial community (Bashir et al 2018;Nie et al 2018) and plants (Mohamed et al 2019).…”

Soil amendment with biochar alleviates the toxic effects of heavy metals on microbial functions in single-metal contaminated soils. Yet, it is unclear how biochar application would improve microbial activity and enzymatic activity in soils co-polluted with toxic metals. The present research aimed at determining the response of microbial and biochemical attributes to addition of sugarcane bagasse biochar (SCB) in cadmium (Cd)-lead (Pb) co-contaminated soils. SCBs (400 and 600 °C) decreased the available concentrations of Cd and Pb, increased organic carbon (OC) and dissolved organic carbon (DOC) contents in soil. The decrease of metal availability was greater with 600 °C SCB than with 400 °C SCB, and metal immobilization was greater for Cd (16%) than for Pb (12%) in co-spiked soils amended with low-temperature SCB. Biochar application improved microbial activity and biomass, and enzymatic activity in the soils co-spiked with metals, but these positive impacts of SCB were less pronounced in the co-spiked soils than in the single-spiked soils. SCB decreased the adverse impacts of heavy metals on soil properties largely through the enhanced labile C for microbial assimilation and partly through the immobilization of metals. Redundancy analysis further confirmed that soil OC was overwhelmingly the dominant driver of changes in the properties and quality of contaminated soils amended with SCB. The promotion of soil microbial quality by the low-temperature SCB was greater than by high-temperature SCB, due to its higher labile C fraction. Our findings showed that SCB at lower temperatures could be applied to metal co-polluted soils to mitigate the combined effects of metal stresses on microbial and biochemical functions.

Purpose This study examines the production of biochar from sugarcane bagasse and olive mill waste, focusing on its elemental composition, form, and functional groups, and its impact on soil immobilization. Methods The study utilized various techniques like SEM, TEM, and FTIR to describe the biochars produced from SCB and OMW, which were prepared through ball-milling and activation treatments. Results The study explores KOH interaction pathways during biomass pyrolysis, revealing larger surface areas and consistent decrease in soil trace element levels. Conclusions This study introduces ZnCl2 chemical activation and activated carbon samples, enhancing understanding of activation procedures and biochar nanoparticles' benefits. It offers a green, sustainable solution to soil contamination.
