“…Also, the conscation of Pb(II) and Cu(II) by an adsorbent derived from chili seed in single and multicomponent systems was studied by Forgionny et al 5 In single component systems, it was observed that the uptake capacity of 48.00 mg g −1 for Pb(II) was greater than the Cu(II) uptake capacity of 4.10 mg g −1 as achieved by the chili seed. This suggests that the chili seed has greater selectivity for Pb(II) ions than for Cu(II) ions in the single sorption systems.…”

“…Therefore, the available advanced methods like SEM/EDX, TGA, FT-IR, XPS and ζ-potential measurements were utilized to estimate the removal mechanism during the adsorption of Cu(II) and Pb(II) ions on the SER surface. Previous studies have revealed that the elimination of these contaminants can be realised by different processes, among which the complexation with surface carboxylic groups, the chelation with nitrogen moieties with formation of a coordinate bond between the lone pair of nitrogen and d-orbitals of heavy metals and the ion exchange are the most common [39][40][41].…”

The presented study proposes a new potential biosorbent- Thymus serpyllum L. (wild thyme) plant, which showed to be highly efficient in rapid adsorption of Cu(II) and Pb(II) ions. Apart from biochars, that are commonly used for adsorption, here we report the direct use of native plant. The highest adsorption capacity for Cu(II) and Pb(II) ions (qe = 12.66 and 53.13 mg g-1, respectively) was achieved after 10 and 30 minutes, respectively. The combination of characterization methods (SEM/EDX, TGA, FT-IR, XPS and ζ-potential measurements) confirmed the combined adsorption mechanism consisting of the ion exchange at the lower Cu(II) and Pb(II) concentrations and the complexation and chelation at higher concentrations. Moreover, the Cu-laden plant has been shown to be an efficient antibacterial agent against the bacteria E. coli and S. aureus. Thus, the sustainable resource can be used both to treat wastewater and be used in the fight against microbes afterwards.

“…So, one of these coexistenced pollutants including heavy metals (such as Pb and Cd) and organic matters (such as TNT, aniline and toluene) had been studied extensively to expolore its characteristics of adsorption on media over decades (Hristov and Hristov, 2017; Lin and Xu, 2020; Pintor et al 2021; Wu et al 2022), and it also was found that the characteristics of adsorption had in uence on the objective pollutant transport in soil and groundwater (Pintor et al 2021;Liu et al 2023). As you known, its surface properties of an adsorbent can cause changed via adsorbing one, thus affecting its adsorption for other pollutants (Zhou et al 2003; Lin and Xu, 2020; Forgionny et al 2021;Liu et al 2023). So, it is reasonable to speculate that the interaction between their adsorptions should inevitably affect their transports in soil and groundwater.…”

Batch adsorption and column tests were conducted to explore characteristics of transports of TNT and aniline and their interactions in saturated Chinese loess sampled from Xi’an, China. Batch tests show that the performances of TNT and aniline adsorptions on Chinese loess are not same when they exist alone. When they coexist, their adsorptions inhibit each other and their inhibitions potentials were different. TNT inhibition on aniline adsorption is in linear and increases with TNT concentration increasing, while aniline inhibition on TNT adsorption also depends on its concentration but in two stages, where the inhibition is few when aniline concentration is lower than 5 mg/L, and then also gets linear increasing with aniline concentration increasing over 5 mg/L. Even though, the inhibition of aniline on TNT adsorption is generally greater than that of TNT on aniline adsorption. Column tests show that, compared with the transport behavior when they exist alone, theier coexistence can promote each other to transport in the saturated loess, importantly, aniline promotes more obviously TNT transport than TNT promotes aniline transport. Kinetics, isotherms and thermodynamics studies indicat that, TNT adsorption is primarily through the surface adsorption while aniline adsorption is mainly via electrostatic adsorption and inner pore diffusion adsorption as well as surface adsorption. There is a certain competitive relationship in their adsorptions on Chinese loess because they have same adsorption sites, meanwhile, they have different adsorption sites, especially, electrostatic force is greater than surface force, when they coexist. So, these inhibitions on adsorption are conducive to the existences of TNT and aniline in the water solution rather than being fixed on Chinese loess, thus enhancing their transports in the saturated loess and aniline has a great effect on TNT migration, while TNT has a small effect on aniline transport, indicating their coexistence can increase the risk of deep soil and even groundwater pollution.
