“…The texture characteristics of sorbents strongly depend on plant type, growing conditions, and biochar production parameters, which vary in extensive ranges. Rice husk biochar is characterized by a range of BET Specific Surface Area from 34 to 774m 2 /g [34][35][36] for sunflower www.nature.com/scientificreports/ residues-from 7 to 434 m 2 /g 22,37,38 for wood raw materials-from 6 to 557 m 2 /g [39][40][41] . Thus, the biochars used in this study are characterized by high texture indicators, suggesting the efficacy of raw materials' applied pyrolysis scheme.…”

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.

“…Compared with other plant materials, woody biochars have been of particular interest since the carbon content in woods is retained in a greater percentage. 22 Also, woodchips are common plant waste in nature, with low cost and wide source. Woodchip-derived biochars played an effective role in removing ionizable organic pollutants including tetracycline, levo-oxacin, sulfamethazine and ibuprofen, [23][24][25] which exhibited a broad application prospect in environmental restoration.…”

“…As a class of environmental contaminants, heavy metals were widely acknowledged as they provide a significant risk to both the health of humans and the ecosystems in which they were found [1]. Pollutants made of metals cannot be broken down by living organisms and have a tendency to build up in the food chain, where they then cause hazardous consequences [2].…”

In this paper, vigna peel was used as a new way to get rid of Cd(II) from its aqueous solutions (VP). For this study, vigna peel (VP) was changed chemically with 25% by volume H2SO4 and ultrasonication at a frequency of 20 kHz to make a high-efficiency adsorbent. In this study, the material found was used to remove Cd(II) from the sample. The SEM and BET methods were used to figure out what the VP material was like. There were different amounts of Cd(II) (10–50 mg/L), pH (1–10), time (5–60 min), and VP dosages (50–1000 mg/50 ml). Maximum Cd(II) removal was found to be 98.6% at pH 5 with 50 mg/L of Cd(II) and 250 mg/50 ml of VP for 15 minutes. Pseudo-first-order, pseudo-second-order, and intraparticle diffusion kinetic models provided the best explanations for the equilibrium data.
