“…17 Peaks at 725.0 and 711.0 eV indicated the presence of iron oxide and hydroxyl oxides such as FeO, Fe 2 O 3 , Fe 3 O 4 , Fe(OH) 2 /Fe(OH) 3 , and FeOOH on the AZVI surface, 18,19 while 706.6 and 720.0 eV were attributed to the Fe 0 peak. 20 For the surface O species, the peaks at 532.4, 531.4, and 529.9 eV were assigned to adsorbed water (�H 2 O), 21 iron hydroxide (Fe−OH), and iron oxide (Fe−O) (Figure 2b). 22 The content of valence state percentage was further calculated by using the peak area.…”

Amorphous zero-valent iron (AZVI) has attracted wide attention due to its high-efficiency reduction ability. However, the effect of different EDA/Fe(II) molar ratios on the physicochemical properties of the synthesized AZVI requires further investigation. Herein, series of AZVI samples were prepared by changing the molar ratio of EDA/Fe(II) to 1/1 (AZVI@1), 2/1 (AZVI@2), 3/1 (AZVI@3), and 4/1 (AZVI@4). When the EDA/Fe(II) ratio increased from 0/1 to 3/1, the Fe 0 proportion on the AZVI surface increased from 26.0 to 35.2% and the reducing ability was enhanced. As for AZVI@4, the surface was severely oxidized to form a large amount of Fe 3 O 4 , and the Fe 0 content was only 74.0%. Moreover, the removal ability of Cr(VI)

“…The N 2 adsorption-desorption curve of FKBC indicates obvious hysteresis loops at high pressure and features of the type-IV model, demonstrating the formation of mesoporous structures. 46 Table 1 shows that the FKBC BET surface area is 19.79 m 2 g −1 , and the total pore volume is 0.126 cc g −1 , 14.8 times and 2.7 times higher than BC, respectively. The FKBC pore diameter is 3.54 nm, smaller than that of BC.…”

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.
