“…Cu(II) and Ni(II) occupied the adsorption sites only once during non-competitive adsorption; but Cu(II) and Ni(II) co-occupied the same sites once during competitive adsorption, indicating an antagonistic effect ( Table 3). These results are in agreement with the works of [34,29,45].…”

“…The Langmuir-type model can fit the single, binary, and multicomponent experimental data of Cu(II) and Ni(II) adsorption very well (R 2 >0.90), indicating homogeneous distribution of these metals onto the surface-active sites of the montmorillonite. This is in agreement with previous works, which have also observed that the Langmuir model described the sorption data best in multimetal systems [15,34,40]. Based on the values of maximum sorption capacities calculated from the fitted Langmuir equation, the sequence of metal sorption was Ni(II)>Cu(II) in non-competence and competence conditions.…”

“…2b). It was clear that sorption of Cu(II) on Na-bentonite was strongly dependent on pH values, as has been already seen by other authors [15,[31][32][33][34]. The sorption increased slowly at pH 4-6 and increased sharply at pH 6-7.…”

Heavy metals such as Cd, Cr, Pb, Cu, Ni, and Zn are commonly found in leachates of solid urban waste [1-3]. Their presence in soils and groundwater near municipal landfills are of main concern when the disposal sites are not properly isolated. Many of these heavy metals are listed on top of the priority pollutants list because of their high toxicity to human health as well as the ecosystems at trace levels [4]. Ni(II) and Cu(II), as representatives of these heavy metals, are chosen for this study as they are present in landfill leachates of different localities and ages. Exposure to high levels of copper in water and diet can lead to diseases of the liver and kidney [5]. The chronic toxicity of nickel to humans

“…The experimental adsorption equilibrium data were obtained in batch-adsorption mode. The experimental procedure was described previously by Bourliva et al (2013b, 2015). In brief, 100 mL of a single metal solution and a pre-weighed clay amount were poured into centrifugal vials and placed on a vertical rotary shaker (10 turns/min) for a desired time interval for equilibrium to be attained, centrifuged at 3000 rpm for 15 min, and the final concentration of each metal was determined by Atomic Absorption Spectroscopy (AAS).…”

Removal of Cu²⁺ and Ni²⁺ ions from aqueous solutions by adsorption onto natural palygorskite and vermiculite

The efficiency of two low-cost, abundant and natural clay minerals, palygorskite and vermiculite, in terms of reducing the concentation of Cu2+ and Ni2+ ions was evaluated here. Natural clay minerals were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), BET specific surface area and pore-diameter analysis. Batch-type experiments were performed and various parameters, i.e. pH, clay amount, contact time and initial metal concentration, that affect adsorption processes were investigated. The adsorption of Cu2+ and Ni2+ ions is pH-dependent, while minor clay quantities were sufficient to achieve high removal efficiencies. Adsorption equilibrium occurred in 60 min and the adsorption kinetics were better described by pseudo-second-order kinetics. Experimental results were analysed by the Langmuir, Freundlich, Dubinin–Radushkevich (D–R), Temkin and Halsey isotherm equations. The release of exchangeable cations (i.e. Ca2+, Mg2+, Na+ and K+) was examined to verify an ion-exchange mechanism.

“…For example, Pádrová et al [12] found that the industrial synthetic adsorbents (e.g., Nanofer 25 and Nanofer 25S) are toxic to the soil microorganisms. erefore, natural adsorbents, naturally formed or derived from natural materials with insignificant risks to the environment, have attracted the attention of researchers again due to their noninvasive properties and low cost [13,14]. e mineral materials (montmorillonite, kaolinite, goethite, etc.)…”

Heavy metals have caused serious environmental issues, which are enriched during open-cast coal mining. It is urgent to develop sustainable remediation materials to protect and restore the contaminated soil and aquifers in mining areas. The feasibility of applying Pisha sandstone (PS) and Na+-modified Pisha sandstone (Na-PS) for adsorption of heavy metals was evaluated. Na-PS exhibited maximum Cd(II) and Cu(II) removal rates of 65.9% and 99.8%, respectively, exceeding the corresponding values for PS (8.2% and 1.3%, respectively) in 1 × 10−3 M solution. Efficient heavy metals adsorption occurred in the pH range 5.0–6.0. The adsorption of Cu(II) and Cd(II) on PS and Na-PS was characterized by kinetic models and adsorption isotherms and was well represented by pseudo-second-order kinetics (R2 > 0.99) and the Langmuir and Freundlich isotherm models. The values of the thermodynamic parameters indicated that the interactions were spontaneous endothermic reactions. Binary solutions adsorption isotherms indicated that the linearity of the adsorption amount and initial concentration of Cu(II) and Cd(II) was better in certain ranges and the adsorbents were selective towards Cu(II) rather than Cd(II). Therefore, PSs can be used as excellent adsorbents for Cu(II) and Cd(II) remediation from contaminated surface water.
