Zemanová V., Trakal L., Ochecová P., Száková J., Pavlíková D. (2014) The results of the model experiment confirmed that the sorption from single-metal solution was more effective than sorption under multi-metal conditions, due to competitive effects. In all tested soils sorption of Cd, Cu and Zn decreased with the rate of other competitive metals; the Pb sorption was not affected by other competitive metals in solutions. Moreover, during multi-metal sorption, Zn was significantly desorbed in Cambisol. In general, sorptions of Cu, Pb and Zn were greater in uncontaminated soil compared to contaminated soils. Clear trend of impact of the contamination on Cd sorption was not observed. The results showed the sorption decreasing in order Chernozem > Fluvisol > Cambisol. The sorption was the greatest in uncontaminated soil with low mobility of studied metals.

“…In addition, Lair et al [35] demonstrated that Strong competition was observed between Cu 2+ and Cd 2+ for the sorption and retention sites in soil and sediment, and the sorption capacity of Cu 2+ ions on the organic material are twice as high as that for Cd 2+ , which resulted in Cd 2+ migration from soil. Cerqueira et al [36] demonstrated the majority of soils have a high affinity for Cu 2+ , more than for Cd 2+ . Meanwhile, they found that the Cu 2+ could make sorption amount of Cd on soil (compared to the individual one) decrease 72 ± 21% (always more than 43%), and desorption amount decline 80 ± 18% (always more than 54%).…”

Sorption is a crucial process that influences immobilization and migration of heavy metals in an aqueous environment. Sediments represent one of the ultimate sinks for heavy metals discharged into water body. Moreover, the particle size of sediments plays an extremely important role in the immobilization of heavy metals. In this study, the sorption and desorption of cadmium (Cd) and copper (Cu) onto sediments with different particle sizes were investigated to predict the rate and capacity of sorption, to understand their environmental behaviors in an aqueous environment. Batch sorption and kinetic experiments were conducted to obtain the retained amount and rate of Cd and Cu in a binary system. Experimental data were simulated using sorption models to ascertain the sorption capacity and the kinetic rate. Results of European Communities Bureau of Reference (BCR) sequential extraction showed the highest concentration of Cd (0.344 mg kg −1 ), and its distribution varied with sediment particle size and site. Furthermore, most of Cu (approximately 57% to 84%) existed as a residual fraction. The sorption of Cu onto six sediments followed a pseudo-first order reaction, whereas that of Cd followed a pseudo-second order reaction. Additionally, the competitive Langmuir model fitted the batch sorption experimental data extremely well. The highest sorption capacities of Cd and Cu reach 0.641 mmol kg −1 and 62.3 mmol kg −1 , respectively, on the smallest submerged sediment particles. The amounts of Cu and Cd desorbed (mmol kg −1 ) increased linearly with the initial concentration increasing. Thus, sediment texture is an important factor that influences the sorption of heavy metal onto sediments.

“…Soil pH, the amount and type of clay minerals, carbonate contents, organic matter, oxides, and eventually simultaneous presence of competing trace elements affect sorption processes and their fate in soils (McGrath et al 1988;Harter and Naidu 2001;Veeresh et al 2003;Bradl 2004;Cerquiera et al 2011aCerquiera et al , 2011b. Despite the sorptive aspect that gives these properties and components to the soil, trace elements can be desorbed from the surface of the soil colloid to the soil solution, and thus absorbed by plants or released to lower soil horizons and groundwater (Evans 1989;Backes et al 1995;Selim 2012).…”

“…Vega et al (2008) stated that K r is a useful parameter for comparing sorption and retention capacity and hysteresis of different soils or materials for trace elements. K r parameter has been used on previous studies of sorption and desorption of trace elements (Vega et al 2009;Cerquiera et al 2011a;Cerquiera et al 2011b;Asensio et al 2014).…”

The sorption and retention processes play an important role in determining the bioavaibility and fate of trace elements in soils. Sorption and desorption of Pb(2+), Zn(2+), Ni(2+), Cu(2+), and Co(2+) in three Tunisian Aridisols Calcorthids (AR1, AR2, and AR3) were studied using batch experiments. Sorption and retention capacities were determined by means of K r parameter and they were related to soil properties. The results showed that in all studied soils, K r values for Pb(2+) and Cu(2+) were higher than those of Zn(2+), Ni(2+), and Co(2+) indicating that soils have higher affinity for the first ones. The high sorption and retention capacity of the three studied soils is ascribed to their alkaline pH and their high carbonates contents favoring the precipitation of these elements. Moreover, bivariate correlation analysis showed that sorption and retention of the studied cations was also strongly correlated with clay fraction and Fe oxides contents. All soils show high sorption irreversibility of Pb(2+), Zn(2+), Ni(2+), Cu(2+), and Co(2+). The soils with highest sorption capacity show also the highest irreversibility.
