“…According to r 2 and SEE values of order kinetic equations, the release kinetic of Zn in soils was poorly described by those models; so the order kinetic models will not be discussed furthermore. This is similar to the results of Boostani et al (2016) and Taghdis et al (2016) who reported that order kinetic models could not adequately describe Zn desorption from calcareous soils. Simple Elovich and two-constant rate models had the highest values of r 2 and the lowest values of SEE; so these models had a good estimation of Zn release from soils (Table 5).…”

“…Simple Elovich and two-constant rate models had the highest values of r 2 and the lowest values of SEE; so these models had a good estimation of Zn release from soils (Table 5). Taghdis et al (2016) with study of Zn desorption from two calcareous soils indicated that time-dependent Zn desorption was best fitted by the simple Elovich, two-constant rate and parabolic diffusion models, respectively. Also, Zahedifar et al (2010) concluded that the two-constant rate, parabolic diffusion, and simple Elovich equations were the best models for describing Zn desorption in their studied calcareous soils.…”

“…It seems likely that the release of Zn is controlled by two different mechanisms. The initial rapid release of Zn from soil represents the release of Zn from readily extractable fraction or adsorption places that have low-binding energy while the slower second phase can be related to a Zn fraction with slower extraction kinetics (Taghdis et al 2016). investigated Zn adsorption of some calcareous soil, and concluded that the best model that can explain Zn adsorption onto these soils was two-surface Langmuir model, therefore, the release of Zn can take place from two sites with different energy levels.…”

“…Study of the kinetic models is a useful procedure to describe changes in nutrients availability over time. These models have been used by several researchers in last decades (Olama et al 2010;Chaudhary et al 2011;Boostani et al 2016;Taghdis et al 2016). Aware of the Zn desorption kinetic in soil may provide important information about the nature of the reaction and also the rate of Zn supply to plant via soil solution .…”

“…Boostani et al (2016) studied the kinetic release of Zn in a calcareous soil and demonstrated that simple Elovich equation was the best model to describe Zn desorption from soil. Also, Taghdis et al (2016) showed that simple Elovich equation was the best model for describing the release kinetic of Zn in two calcareous soils; but Padidar (2015) indicated that the amount of Zn desorbed from the studied soils was poorly described by the simple Elovich equation and soil properties such as CaCO 3 content, organic matter (OM) content, and soil pH were the effective factors on Zn release from the soils. Zahedifar et al (2010) reported that the constants for the two-constant rate model were closely correlated with cation exchange capacity (CEC), OM content, and soil pH in some calcareous soils of Iran.…”

Zinc (Zn) desorption is an important process to determine Zn bioavailability in calcareous soils. An experiment was performed to assess the pattern of Zn release from 10 calcareous soils of orange orchards, southern Iran and the soil properties influencing it. For Zn desorption studies, soil samples were extracted with diethylene triamine penta-acetic acid solution at pH 7.3 for periods of 0.083-48 h. Suitability of seven kinetic models was also investigated to describe Zn release from soils. Generally, Zn desorption pattern was characterized by a rapid initial desorption up to 2 h of equilibration, followed by a slower release rate. The simple Elovich and two-constant rate kinetic models described Zn release the best, so it seems that Zn desorption is probably controlled by diffusion phenomena. The values of the rate constants for the superior models were significantly correlated with some soil properties such as soil organic matter (SOM) content, cation exchange capacity (CEC), and soil pH, whereas carbonate calcium equivalent and clay content had no significant influence on Zn desorption from soils. SOM had a positive effect on the magnitude of Zn release from soils, while soil pH showed a negative effect on Zn desorption. Furthermore, the initial release rate of soil Zn is probably controlled by CEC in the studied soils. Finally, it could be concluded that SOM, CEC, and soil pH are the most important factors controlling Zn desorption from calcareous soils of orange orchards, southern Iran. Abbreviations: Soil organic matter (SOM); Cation exchange capacity (CEC); Calcium carbonate equivalent (CCE); Zinc (Zn).

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.
