“…Other minerals that are typically formed in acid mine drainage systems are Fe and Mn oxides. In both cases, Cu can bind strongly to the surface of oxides formed with these metals [38]. Furthermore, precipitation in natural systems generates initially amorphous minerals, which may have a greater capacity of sorption by affinity with the binding sites to other minerals [39,40].…”

Acid mine drainage (AMD) is an environmental concern characterized by low pH and high concentrations of dissolved metals and sulfate. Yerba Loca Creek in Santiago, Chile, is an AMD-affected water stream that originates in a glacier and, therefore, has a season-dependent flow. This water course is characterized by low pH (3.75 ± 0.13) and high concentrations of aluminum (2.2-2.6 mg/L) and copper (4.8-6.5 mg/L). A field campaign was carried out to study the geochemical behavior around the confluence of the Yerba Loca Creek with the San Francisco River, which has a neutral pH and low concentration of dissolved metals. The results show that the geochemical parameters after the confluence are very similar to those registered for the Yerba Loca Creek, due to its great flow in relation to the San Francisco River. The pH after the mixing zone was controlled by the geochemical conditions and flow of the Yerba Loca Creek; however, the turbidity decreases and stabilizes downstream. We found that, despite the low impact of pH on the precipitation of aluminum and copper phases due to poor neutralization, the dissolved aluminum and copper concentrations are slightly decreased after the mixing zone by natural microscale removal processes or suspended solids formation. Scanning electron microscopy-energy-dispersive X-ray spectroscopy (SEM-EDX) analysis of suspended solids indicates the presence of various oxides, hydroxy-sulfates and aluminosilicates, which have a great affinity for adsorption and co-precipitation with dissolved metals (i.e., Al and Cu). A pH-neutralization would favor the formation of more minerals and, therefore, the immobilization of the heavy metals found in these waters. These results contribute to a better understanding of the effect of the confluence of water courses related to pollution by AMD. It is possible that the seasonal variation of the flows has an impact on the composition of water and minerals formed. River (pH~7.2) [4]. At high elevations of the Yerba Loca Basin, there is a large deposit of copper porphyry, which have long influenced the surface water quality of the area, particularly in terms of pH, sulfate content and mineral concentrations [5]. In particular, in the Yerba Loca Creek acidic conditions and metal content, mainly copper (Cu) and aluminum (Al) [6], have a substantial impact on the vegetation of the area since these waters are highly toxic for most plant species [5]. Furthermore, the presence of Cu in excessive concentrations is harmful to a variety of living organisms such as microorganisms, fish and humans [7]. In the environment, Cu is commonly presented as a divalent cation and is generally more mobile in acidic conditions, while at pH above 7, it tends to form minerals like Cu carbonates and hydroxyl-carbonates [8,9]. Al is the third most abundant element in the Earth's crust and is commonly present as Al oxide and Al silicate [10,11]. At pH less than 6, Al can be leached from the soil and sediments in the water [10], but the solubility increases when pH is less than 4.5 [12...

“…Dolomite also was greater in combination with Ultisols from Tamansari having performed at 91.40% paralleled with activated carbon 90.92% and organic fertilizer 89.68% in that order, combined with the same soil type. However, it is believed that clayey soils, and those containing Iron oxides like Ultisols from Tamansari, can immobilize metals, requiring higher amounts of dolomite or other limes compared to sandy and loamy soils (Suda & Makino, 2016). Similar findings were revealed by Reddy et al (2014).…”

“…Even though, the lower mobile Cadmium in soils can be justified by the content of organic matter (3.08 %, table 1). On the other hand, Alfisols may contain Iron oxides that also adsorb heavy metals (Suda and Makino 2016). Although the organic mater content is low in Alfisols, it is still by far higher compared to other soils, which in turn has high CEC value and clay content.…”

The soil is an important resource, which sustains life on the planet. However, its contamination with Cadmium (Cd) may represent a huge threat to all the chain of living beings. Efforts have been done to minimize soil pollution with trace metals, as well as to amend those soils that are already polluted. This study was conducted aiming to determine the efficiency of three binding agents on the immobilization of Cd in three soil types collected from Karanganyar. Soil samples were collected from the topsoil (30 cm) and analyzed in the laboratory for pH, SOM, CTC, soil texture and initial Cd content before treatment. The experimental design was Completely Randomized (3 soil types; 3 adsorbents; 3 replications), and incubated for 24 days in the laboratory. After incubation, pH and Cd content were measured and ANOVA and Tukey's test were performed. The results showed that Dolomite was the best binding agent on immobilization of Cd (95.45%) in each soil, followed by organic fertilizer (92.64%) and charcoal (91.53%). However, in general, all the binding agents showed remarkable efficiency on Cd immobilization in the three soil types. To sum up, this research may positively boost agricultural systems, which is determinant for sustainable development, in particular in developing countries worldwide. In addition, the outcomes may have a great impact on the reduction of soil pollution with agrochemicals and heavy metals. On the other hand, there is a potential to keep and restore ecological sustainability. Apart from this, also could minimize to some extent, climate change and global warming issues through multi-planting strategies, while significantly contributing to achieving food security and economic stability, as well as addressing poverty issues in rural areas.

“…In comparison with single mineral studies, very few studies have been done to investigate the As adsorption and desorption onto mixed soil minerals (Masue et al, 2007; Wu et al, 2015; Ying et al, 2012; Ying et al, 2013; Zhang et al, 2014; Zhang et al, 2007). In the natural environments, Fe oxides coexist with Mn oxides, and the abundance of Fe oxides is generally higher than that of Mn oxides (Suda and Makino, 2016). The Fe–Mn nodules are common in luvisols, and some may have Fe/Mn ratio < 1 (Palumbo et al, 2001).…”

Adsorption and desorption kinetics of As(V) on Fe and Mn oxide mixture was studied. A predictive kinetics model based on component additivity approach was developed. The kinetics model predicted the kinetic data of As(V) well for the mixed oxides. Ferrihydrite and δ‐MnO2 controlled As(V) reaction kinetics differently. Arsenate [As(V)] soil contamination is a great concern worldwide because of its high toxicity, carcinogenicity, and mobility. The adsorption of As(V) on soil minerals such as ferrihydrite and δ‐MnO2 controls the transport and bioavailability of As(V) in the soil environment. A large number of studies have investigated the equilibrium and mechanisms of As(V) adsorption onto ferrihydrite and δ‐MnO2 individually. However, both ferrihydrite and δ‐MnO2, commonly coexisting within soils has been overlooked and little information is available for the kinetics of As(V) adsorption and desorption in this mixed mineral system. Therefore, in this work, kinetics of As(V) adsorption and desorption onto ferrihydrite and δ‐MnO2 mixed minerals is studied using the stirred‐flow method. A kinetics model for the mixed mineral system was developed using the component additivity approach, which incorporated the nonlinear binding of As(V) to both ferrihydrite and δ‐MnO2 simultaneously. The kinetics model successfully predicted the kinetics of As(V) adsorption and desorption in the mixed mineral system under varying solution chemistry conditions and properly accounted for the heterogeneity of the binding sites of both ferrihydrite and δ‐MnO2. For As(V) adsorption kinetics, the ferrihydrite bidentate non‐protonated sites (Fh‐bi‐np) played a dominant role, followed by the δ‐MnO2 binding sites and the ferrihydrite bidentate protonated sites (Fh‐bi‐p). After the 4‐h desorption, As(V) was mainly retained on ferrihydrite binding sites. This study helps to quantitatively elucidate the kinetic behavior and mechanisms of As(V) in the Fe oxide and Mn oxide systems, thus enhancing our understanding of the fate and transport of As in soil environments.
