“…1 b). The results confirmed that the PS had been mechanochemically doped into the Fe-Mn hydroxide, which covered the change of spectra caused by Fe/Mn ratios (Cao et al 2017). Furthermore, the peaks within the bands of 592 -690 cm -1 and 1060 -1274 cm -1 gradually disappeared with the increase of the PS/Fe-Mn ratio (Fig.…”

“…Given the high toxicity and severe pollution of Sb, many technologies have been developed to remove Sb from water in recent years, such as coagulation [6,7], adsorption [8,9], membrane [10], and electro-coagulation [11] related technologies. For example, many adsorbents were applied to remove Sb, such as goethite, diatomite, and Fe-Mn binary oxide [12].…”

The effectiveness of antimony (Sb) removal by using iron-based coagulants was investigated in this study. The effects of pH, coagulant types and dose, equilibrium concentration, co-existing humic acid (HA) and anions, and oxidation process were studied. Effective Sb removal was achieved by using Fe(III)-based coagulants. However, the removal efficiency of Sb by using Fe(II)-based coagulants was very low. The removal capacity of Sb fitted the Sips adsorption isotherm well, which revealed that the heterogeneous adsorption process onto the formed hydrous ferric oxide played an important role in Sb removal, and the mechanism was further supported by Fourier transform infrared spectrum analysis. Sb removal was inhibited by the presence of HA and phosphate, as well as oxidation and aeration. Therefore, coagulation by using Fe(III)-based coagulants without oxidation is an effective and promising method for removing Sb in aqueous solution.

“…The adsorption capacity of As(III) and As(V) was 1.5 and 0.7 mmol•g − 1 , respectively, which was larger than that of other oxides (Otgonjargal et al, 2012). Fe-Mn-LDH has also been shown to be conducive to the adsorption of Sb(V) (Cao et al, 2017). FTIR and XPS results showed that Sb(V) was removed mainly through adsorption on the surface of Fe-Mn-LDH.…”

With illegal discharge of wastewater containing inorganic and organic pollutants, combined pollution is common and need urgent attention. Understanding the migration and transformation laws of pollutants in the environment has important guiding signi cance for environmental remediation. Due to the characteristics of adsorption, oxidation and catalysis, manganese minerals play important role in the environment fate of pollutants. This review summarizes the forms of interaction between manganese minerals and metals, the environmental importance of the interaction between manganese minerals and metals, and the contribution of this interaction in improving performance of Mn-based composite for environmental remediation. The literatures have indicated that the interactions between manganese minerals and metals involve in surface adsorption, lattice replacement and formation of association minerals. The synergistic or antagonistic effect resulted from the interaction in uence the puri cation of heavy metal and organism pollutant. The synergistic effect bene ted from the coordination of adsorption and oxidation, convenient electron transfer, abundant oxygen vacancies and fast migration of lattice oxygen. Based on the synergy, Mn-based composites have been widely used for environmental remediation. This review is helpful to fully understand the migration and transformation process of pollutants in the environment, expand the resource utilization of manganese minerals for environmental remediation.
