“…The arsenate is AsO 4 3– under weak acidic conditions and AsO 3 3– under weak basic conditions. − Scheinost and Guo found that the SbO 6 octahedron and FeO 6 octahedron were bonded to form a bidentate mononuclear sharing structure and adsorbed on the surface of the iron oxide As a typical clay mineral, kaolinite is also a typical coexisting phase of heavy metals. Ilgen and others found that Sb(III) and Sb(V) interacted with the edge sites of kaolinite surface to form monodentate or bidentate shared complexes (Figure e). ,, Chen et al found that Cd 2+ was adsorbed on the surface of kaolinite predominantly in the form of bidentate binuclear complexes on the Kln-Al(001) surface (Figure d) …”

Heavy metal containing solid wastes (HMSWs), the byproduct from industrial activities, bring severe environmental issues and health risks to human. Separating heavy metals from HMSWs for resourcing is the most effective way to mitigate their environmental risk. However, the composition of HMSWs is of great complexity, including various heavy metals with relatively low concentration, as well as coexisting phases with different types and inhomogeneous microstructures. These complexities lead to strong interactions between heavy metals and coexisting phases, causing the incomplete separation of heavy metals. Therefore, understanding their microinteractions is a necessary precondition to realize the full resourcing of HMSWs. This Review focuses on recent achievements for analyzing such microinteractions. Advanced characterization techniques are summarized, by which a multidimensional analysis method is put forward. Then, microinteractions of heavy metals with coexisting phases are clearly discussed, and three typical interactions of aggregation/encapsulation, adsorption, and substituted doping are prudently summarized. It is expected that developing targeted methods to destruct the above interactions is an efficient way to improve the heavy metal separation. Therefore, this Review will provide a sufficient understanding of microstructures in complex HMSWs, which is further expected to promote the technological development on decontamination of HMSWs.

“…1,2 The discharge of Sb into aquatic environments originates from the weathering of sulfide ores and anthropogenic activities. 1 In contaminated sites, the total Sb concentration in soil pore water and groundwater can even reach 30 mg L −1 (Table S1 †), 1,3 which is several orders of magnitude higher than the maximum contaminant limit (MCL) for Sb in drinking water (5 μg L −1 ) set by the World Health Organization (WHO). 4 Sb typically exists in two oxidation states, namely Sb(III) and Sb(V), and their presence is closely tied to ambient conditions such as pH and redox potential.…”

We present a novel structure of PA-GO composite /MnO2/Fe3O4/n-Si arranged by simple technique and examined by scanning electron microscope, X-ray diffraction, and Raman spectroscopy. The negative dielectric constant appeared for all voltages at frequencies of 103, 102, 10 Hz, proving that the dielectric constant has negative values only at frequencies above one megahertz 106Hz. Also, the dielectric loss has negative values with temperature at all voltages and high frequencies. This structure also has a low dielectric loss tangent from 4 to 50 with all voltages and temperatures and high rectification ratio reach to 1200 times, and high Rj. The performance of dielectric constant, dielectric loss, and dielectric loss tangent depend on the change of frequencies and voltages. The electrical properties of this structure were examined by conventional, dv/dlnI, and the Nord and Cheung method. The ideality factor fluctuates between 3.09 and 3.29, and the barrier height is in the range of 0.56 to 0.58 at room temperature. We found similar results using different methods of measuring the electrical properties. This indicates that the structure is a promising material for preparing diodes, supercapacitor, and high storage devices.
