“…Biphasic pattern of heavy metals desorption was observed by other (Sadegh et al, 2012;Jalali and Sajadi Tabar, 2013 Ghasemifasaei et al, (2013) studied kinetics of Ni desorption from calcareous soils and reported that power function, first order, and second order equations were the best-fitted equations used to describe Ni desorption. Increasing order of reaction from zero to third caused the R 2 decreased in soils studied, which reported by Sadegh et al (2012).…”

A laboratory study was planned to delineate the benefits of some low-cost soil amendments on Nickel (Ni) stabilization in a Ni-spiked soil. Six different kinds of amendments were evaluated by desorption kinetic test and sequential extraction procedure to determine their ability to reduce mobility of Ni in a Ni-spiked soil. The Ni-spiked soil was separately incubated with coal fly ash (CFA), rice husk biochars prepared at 300°C (B300) and 600°C (B600), municipal solid waste compost (MSWC), zero valent iron (Fe

“…The release rate of Zn and Pb is an important property of soil that determines the ability of soil to introduce metals to the solution (Sadegh et al, 2012;Zahedifar et al, 2012;Motaghian and Hosseinpur, 2013;Mohseni et al, 2018;Boostani et al, 2019). Meanwhile, biochars produced at various temperatures have different properties and could change the distribution and release kinetics of Zn and Pb from highly polluted calcareous soils.…”

“…However, in our study, treatments with more "a e " and less "1/β" had a slower release rate. Sadegh et al (2012) reported that the values of "a e ", "a", and "a × b" constants increased after the addition of poultry manure in calcareous soils. The downward trend of "a e " (derived from the simplified Elovich equation) was observed in the experiment of Zahedifar et al (2012).…”

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.
