“…These findings, on the other hand, revealed that the K d values of heavy metals decreased in CS when compared to MS. This was consistent with previous findings that competitive sorption of metals was lower in competitive systems than in mono-metal systems (Baghenejad et al, 2016;Oladipupo Azeez et al, 2018;Shaheen et al, 2012;Shaheen et al, 2013;Shaheen et al, 2015). A surface-active site can sorb different ions, but once an ion has been adsorbed, no other ions can be adsorbed at the same active site.…”

“…Furthermore, several studies have shown that the sorption systems are affected by the type of soil and metal elements involved (Li et al, 2017). Oladipupo Azeez et al (2018) found that under the MS experiment, Pb had the highest K d value in both acid and alkaline soils, Zn had the highest K d value in slightly acid soil, and Cu had the lowest K d value across the three soil types. While in the CS experiment, Zn and Cd had the highest and lowest K d value, respectively, across the three soil types.…”

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.
