“…The high Ni concentration behind the PRB persisted until the experiment was completed. Other studies have revealed that the adsorption of Ni is far less than those of Cr and Cu under multiple competitive adsorption conditions (Liu et al 2006;Liu et al 2009;Liu et al 2012aLiu et al , 2012b. At the sampling point of the first sand zone, the Ni concentrations exceeded the control standard by 4 to 6 times during most of the reaction time.…”

“…An important consideration in PRB design is the selection of the reactive material. Various adsorbent media, including zerovalent iron (Henderson & Demond 2007;Chen et al 2011;Singh & Singh 2018;Hu et al 2019aHu et al , 2019b, zero-valent aluminum (Han et al 2016), zeolite (Statham et al 2016), fly ash (Czurda & Haus 2002), biochar (Hu et al 2019a(Hu et al , 2019b, activated carbon (Liu et al 2012a(Liu et al , 2012bSingh & Singh 2018), waste green sand, peat (Guerin et al 2002;Erto et al 2011), and even mixed adsorbents (Kumarasinghe et al 2018;Mittal et al 2021) are widely used in groundwater remediation. PRB is considered a practical approach to treat heavy metal ions that contaminate subsurface water owing to its low cost, high efficiency, and environmental friendliness (Dong et al 2009).…”

Heavy metal contamination in underground water commonly occurs in industrial areas in Taiwan. Wine-processing waste sludge (WPWS) can adsorb and remove several toxic metals from aqueous solutions. In this study, WPWS particles were used to construct a permeable reactive barrier (PRB) for the remediation of a contaminant plume comprising HCrO4−, Cu2+, Zn2+, Ni2+, Cd2+, and AsO43− in a simulated aquifer. This PRB effectively prevented the dispersals of Cu2+, Zn2+, and HCrO4−, and their concentrations in the pore water behind the barrier declined below the control standard levels. However, the PRB failed to prevent the diffusion of Ni2+, Cd2+, and AsO43−, and their concentrations were occasionally higher than the control standard levels. However, 18% to 45% of As, 84% to 93% of Cd, and 16% to 77% of Ni were removed by the barrier. Ni ions showed less adsorption on the fine sand layer because of the layer's ineffectiveness in multiple competitive adsorptions. Therefore, the ions infiltrated the barrier at a high concentration, which increased the loading for the barrier blocking. The blocking efficiency was related to the degree of adsorption of heavy metals in the sand layer and the results of their competitive adsorption.

“…Hence the removal and recovery of these metals from wastewater streams is important. Numerous metals such as chromium, cadmium, copper, lead and mercury have toxic effects on both human and environment (Taty-Costodes et al, 2003;Liu et al, 2012). Copper is a widely used material and there are many actual or potential sources of copper pollution.…”

: Soil clays (< 2,000 nm) (SC) and soil nanoclays (< 100 nm) (SNC) were used as adsorbents for removal of Cu(II) from aqueous solution. The experiments were conducted with variables including pH, interaction time, concentration of Cu(II) and temperature. Four kinetic models have been employed to investigate adsorption mechanisms, and the experimental data more closely resemble a second‐order process of the kinetic model. Adsorption studies on soil nanoclays have been shown to be highly effective in removing of Cu(II) from aqueous solution. This adsorbent is widely available as a natural material, is mechanically stable and, most importantly, it is environmentally appealing. The maximum Cu(II) adsorption capacity of soil nanoclays (31.7 mg/g) is more than three times higher than natural soil clays (10.2 mg/g). Our study demonstrates that soil nanoclays can be used effectively for removal of Cu(II) from aqueous systems to achieve environmental cleaning purposes.

Drainage canal sediments in an industrial park are generally dredged to landfill in Taiwan. The objective of this study was to evaluate feasibility employing the sediment as an adsorbent for removal of dye. The sediment contained approximately 10% of organic matter and little heavy metals. Infrared (IR) analysis revealed that carboxyl was the most important functional group for methylene blue (MB) sorption. Canal sediment could remove the most MB from water at pH 8.0 and this removal increased with increasing temperature. The MB sorption was well described by the Langmuir, Dubinin-Radushkevich, and Temkin sorption isotherms at 10°C, but it showed good compliance with Freundlich isotherm at 25°C and 40°C. The MB adsorption was a spontaneous and endothermic reaction; its maximum calculated adsorption capacity (Q) was 56.0 mg g at 10°C by the Langmuir isotherm. The calculated values of enthalpy (ΔH°) and entropy (ΔS°) are 14.6 kJ mol and 149.2 kJ mol, respectively. Only pseudo-second-order adsorption kinetic model successfully described the kinetics of MB onto the sediment at different operation parameters. Activation energy of MB adsorption calculated from Arrhenius equation was 16.434 kJ mol, indicating the binding between canal sediment and MB was a physical adsorption.
