“…However, when its concentration exceeds a critical value, it is considered a toxic element that can contaminate soil, water, and food chains (Noulas et al, 2018). Many studies have shown that the K d values of Zn are influenced by both Zn properties (added Zn initial concentrations, and sorption systems) and the soil properties (such as soil type and texture, pH, clay content, organic matter, iron, and manganese oxides) (Das & Das, 2015;Gurpreet et al, 2012;Piri et al, 2019;Swati & Hait, 2017;Urbaniak et al, 2017;Vithanage et al, 2017). Generally, the K d values of Zn decrease with the increase of added Zn initial concentrations (Azouzi et al, 2015).…”

This review synthesizes the methods for estimating the distribution coefficient (K d ) and provides a compilation of K d values for five heavy metals (As, Pb, Cd, Cu, and Zn) based on research published in the last decade (2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019)(2020)(2021). We used the PRISMA method to ensure the transparency of the collected data. For mono-metal systems (MS), the K d values ranged from 10 −2 to 10 7 L/kg for Pb, from 10 −2 to 10 6 L/kg for Cd, As, and Zn, and from 10 −2 to 10 5 L/kg for Cu. In competitive systems (CS), the K d values ranged from 10 −2 to 10 5 L/kg for Cu, and 10 −2 to 10 4 L/kg for Pb, Cd, and Zn, while no K d value for As was reported under CS. It was found that the K d values of heavy metals are affected not only by soil chemical and physical properties but also by the nature and characteristics of the metal involved along with experimental conditions. The totals references number of K d data observation per element metal are represented as follows: Cd 35 (50%), Zn 35 (50%), Pb 33 (47.14%), Cu 33 (47.14%), and As 19 (27.14%). Overall, most research was done 1) on MS rather than CS, 2) on sorption rather than desorption, 3) on soil rather than sediments , and 4) most literature have reported the K d values, derived from batch method than on column method. Despite significant progress over the past decade towards a better understanding of the variation in K d values and the effect of factors influencing them to provide important parameters for predicting and controlling toxic metals in soils, additional research is still warranted to the complexity of underlying processes.

“…In order to investigate the mechanism and fundamentals of methylene blue adsorption onto the BiFeO 3 /biochar coupled magnetic beads, the experimental data were fitted with three isothermal models: Langmuir, Freundlich, and Temkin [47]. The data of the relevant adsorption isotherms obtained after fitting were analyzed, and the results are shown in Figure 13.…”

Biochar obtained by pyrolysis of the fiber plant kenaf was mixed with bismuth ferrite (BiFeO3) in a chitosan-containing acetic acid solution, magnetized, and modified to prepare a chitosan-crosslinked BiFeO3/biochar coupled magnetic material. The adsorption properties of the composite were investigated using methylene blue dissolved in water, and the effects of external conditions, such as pH, methylene blue concentration, reaction time, and temperature, on the adsorption performance were studied. The adsorption data were fitted and analyzed with kinetic and isotherm models, and the results showed that the BiFeO3/biochar coupled magnetic material effectively adsorbed methylene blue. The amounts adsorbed onto this magnetic material increased with increasing initial methylene blue concentration, reaction time, and temperature, and the adsorption performance improved under neutral and alkaline conditions. The pseudo-first-order kinetic and Langmuir isotherm models satisfactorily fitted the adsorption data, showing that the adsorption of methylene blue involved both chemical and physical adsorption. The maximum adsorption capacity of methylene blue onto the BiFeO3/biochar coupled magnetic material reached 18.942 mg·g−1 at 25 °C, confirming the excellent dye binding activity of this material.

“…In addition, the free carboxyl groups in sulfonated lignite can increase the hydrophilicity of a mineral surface after chelating with metal ions, so it is often used as a pressure-reducing agent [ 5 ]. However, in sulfonated lignite, there are abundant functional groups (including phenolic hydroxyl groups, carboxyl groups, ketones, and sulfonic acid groups), as well as active groups that will inevitably lead to the characteristics of high chemical oxygen demand, high biochemical oxygen demand, and high sulfur content in drilling wastewater [ 6 , 7 , 8 ]. In addition to its unfavorable color and taste, sulfonated lignite is a catching agent of heavy metals, pesticides, and herbicides, and it can increase their concentration in water, thereby breeding more bacteria [ 9 ].…”

In this study, hierarchical MgAl-LDH (layered double hydroxide) nanoparticles with a flower-like morphology were prepared under a hydrothermal condition by employing worm-like micelles formed by cetyltrimethylammonium bromide (CTAB) and salicylic acid (SA) as templates. The morphology and structure of the materials were characterized by Brunauer–Emmett–Teller (BET), SEM, and XRD analyses. The performance for the adsorption of sulfonated lignite (SL) was also investigated in detail. FTIR was used to detect the presence of active functional groups and determine whether they play important roles in adsorption. The results showed that the hierarchical MgAl-LDH nanoparticles with a specific surface area of 126.31 m2/g possessed a flower-like morphology and meso–macroporous structures. The adsorption capacity was high—its value was 1014.20 mg/g at a temperature of 298 K and an initial pH = 7, which was higher than traditional MgAl-LDH (86 mg/g). The adsorption process of sulfonated lignite followed the pseudo-second-order kinetics model and conformed to Freundlich isotherm model with a spontaneous exothermic nature. In addition, the hierarchical MgAl-LDH could be regenerated and used, and the adsorption was high after three adsorption cycles. The main adsorption mechanisms were electrostatic attraction and ion exchange between the hierarchical MgAl-LDH and sulfonated lignite.
