“…Thus, the larger levels of biochar produced at higher temperatures diminished metals in the forms of exchangeable, carbonate, Fe-Mn oxides, and enhanced metals trapped in organic matter and residual fractions. According to the results, which are similar to our previous study, biochars would alter the metals' distributions in a way that they declined readily available forms (exchangeable, associated with carbonates, and associated with Fe-Mn oxides), but raised less reachable sites (associated with organic matter and residuals) in the soil (Kabiri et al 2019). Similarly to the present research, Karimi et al (2020) reported that the application of 2% corn residue biochar produced at 500°C decreased DTPA-Zn in a calcareous soil.…”

“…The pseudo-total Zn and available Zn were 35.758 and 228.8 mg kg −1 , respectively, while the pseudo-total Pb and available Pb were 7933 and 432.8 mg kg −1 , respectively. The contents of total nitrogen, available P, and K were 0.015%, 13.07, and 43 mg kg −1 , respectively (Kabiri et al, 2019).…”

“…The CEC of the walnut leaves exceeded that of biochars (30.5 cmol + kg −1 ). It was in descending order for a greater temperature of biochars (B200 (28.5 cmol +kg−1) > B400 (22.9 cmol + kg −1 ) > B600 (19.9 cmol + kg −1 )) (Kabiri et al, 2019); thus, our previous experience documented that higher pyrolysis temperatures increased pH, ash content, BET, and aromaticity, which were the most important characteristics affecting adsorption and release of PTEs in soil according to previous results (Dokht et al, 2017).…”

“…Soil has drastically become a major reservoir of potentially toxic trace elements (PTEs) due to indiscriminate man-made endeavors, especially when extracting valuable minerals or geological materials from the ground in mining areas (Kabiri et al, 2019;Lahori et al, 2020;Feng et al, 2020). Potentially toxic trace elements can reach the food supply, contaminate microbiota and macrobiota, and ultimately increase hazards to human beings (Lahori et al, 2019).…”

“…As is prepared inside a sealed container with no or very low air pressure, biochar finds its extraordinarily high organic carbon in a polarity aromatic structure and high oxygen-containing acid group content in order to grasp PTEs with higher sorption efficiency than other organic matters (Wang et al, 2015;Abdallah et al, 2019). Studying Zn and Pb fractionation and phytotoxicity in naturally calcareous and highly polluted soil, Kabiri et al (2019) concluded that biochar reduced Zn and Pb content in plant tissues and promoted gradual maize growth responses through modifying metals' fractions. They stated that biochars fractioned Zn and Pb from readily available partitions (soluble, exchangeable, associated with carbonates, associated with Fe-Mn oxides) to less accessible forms (associated with organic matter and residual).…”

Release kinetics governs the detachment and migration of potentially toxic trace elements (PTEs) over time between the solid phase and soil solutions. The assessment of PTEs' release behavior through time supports more accurate prediction models of toxicity in highly polluted soils. Recently, biochar, a charcoal black carbon ameliorant, was extensively applied for decreasing the release of Zn and Pb to the soil solution. This study was arranged during a short-term (45 days) incubation experiment to estimate the possible effects of walnut leaves (WL) and their biochars produced at three temperatures (200 (B200), 400 (B400), and 600 (B600)°C) on the kinetics of Zn and Pb release in a naturally calcareous and highly polluted soil. Results showed that the biochars could reduce the release of Zn and Pb to the soil solution. The rate of Zn release ("b" in power function) at different biochar levels was 0.35 (2% B600)-0.38 (control) (mg kg −1) −1 , respectively; also, the release of Pb was 0.23 (2% B600)-0.33 (control) (mg kg −1) −1 , respectively. The results illustrated that a lower concentration of these metals was associated with exchangeable and oxides of Fe-Mn, whereas the higher content of residual fractions of Zn and Pb reduced the release of Zn and Pb in soils treated with biochar. Overall, the more the level and temperature of biochar increased, stabilizing PTEs through changing the distribution of metals in the soil, the more biochars succeeded significantly in lessening the release of PTEs, which ultimately could retard the further toxicity in the soil solution.

In order to prepare a new adsorbent material for the treatment of waste water containing Pb(II), hyperbranched polyamide-amines (H-PAMAMs) were prepared via one-pot method, then the H-PAMAMs were crosslinked by epichlorohydrin. The crosslinked hyperbranched polyamide-amines (C-H-PAMAMs)were prepared and characterized. The selective adsorption of coexisting ions shows that the C-H-PAMAMs have high adsorption capacity and selectivity for Pb(II). The adsorption characteristics and mechanism of the C-H-PAMAMs for Pb(II) were systematically investigated. The results of batch adsorption experiments showed that the maximum Pb(II) adsorption capacity was 180.83 mg/g at pH 4.0 and 318 K. The adsorption process on the C-H-PAMAMs was well described by the Langmuir model, which indicated the adsorption process was spontaneous and endothermic. The X-ray photoelectron spectroscopy analysis showed that the adsorption mechanism of the C-H-PAMAMs for Pb(II) was the synergistic chelation of COO and CO NH . Four adsorption/ desorption recycling tests showed that the the C-H-PAMAMs still had a high adsorption capacity for Pb(II).
