AB  - A series of goethite-modified montmorillonite (GMt) materials was synthesized for the amelioration of cationic
cadmium (Cd) and anionic arsenic (As) complex contaminants in soil and water bodies. The results showed that
goethite (Gt) was successfully loaded onto the surface of montmorillonite (Mt), which possessed more functional
groups (such as Fe–O, and Fe–OH) and a larger specific surface area. GMt-0.5 (Mt loaded with Gt at a ratio of
0.5:1) showed the highest adsorption capacity for Cd(II) and As(III) with the maximum of 50.61 mg/g and 57.58
mg/g, respectively. The removal rate of Cd(II) was highly pH dependent, while the removal rate of As(III)
showed little dependence on pH. The goethite on montmorillonite might contribute to the formation of surface
complexes with As(III) and oxidation of As(III) to As(V). In the binary system, both, synergistic and competitive
adsorption existed simultaneously. Importantly, in the binary system, the removal of As(III) was more favorable
because of the electrostatic interaction, formation of a ternary complex, and co-precipitation. In addition, the
amendment of GMt-0.5 significantly reduced the availability of Cd and As in the soil. This study suggests that
GMt-0.5 is a promising candidate for the simultaneous immobilization of metal (loid)s in both, aqueous solution
and mine soil.

AB  - The organic pollution generated during production and processing in the mining area seriously endangers the ecological security of the surrounding environment. In this study, degradation of α-nitroso-β-naphthol (αNβN), a typical organic flotation reagent in mining area, by using steel converter slag (SCS) as a low-cost catalyst was reported for the first time. The results showed that SCS + H2O2 could effectively remove αNβN from water solutions. In the system used in this study, more than 98.8 % of αNβN could be removed within 60 min. Based on the analysis of the experimental results, the synergistic mechanism of radical and non-radical pathways was proposed. The radical pathway mainly consisted of [rad]OH radical oxidation, while the non-free radical pathway consisted of 1O2 and electron transfer. Fe, bridging OH and terminal OH on the surface of SCS were the active sites for H2O2 activation. The removal performance of the system was not affected by common coexisting ions, and showed strong anti-interference ability. After 4 times repeated use, the removal efficiency still reached more than 83 %. HPLC-MS was used to analyze the intermediate products, while the changes in their toxicity effects were analyzed by microcalorimetry for the first time. The results showed that the system could effectively reduce the ecotoxicity of a water solution containing αNβN. This study provides not only a new strategy for treating organic pollution in mining areas, but also a new idea for the green cycle development of industry and mining from the perspective of “treat the wastes with wastes”.

AB  - In this work, the immobilization stabilization and mechanism of heavy metal(loid)s by goethite loaded montmorillonite (GMt) were investigated, and the soil microbial response was explored. The simulated acid rain leaching experiment showed that GMt had a higher acid tolerance and the more stable heavy metal(loid)s fixation ability. The soil incubation demonstrated that GMt significantly decreased the available Cd, Zn, Pb and As concentration. Interestingly, higher immobilization of heavy metals was observed by GMt in highly acid leached and acidic soils. The richness and diversity of bacterial communities improved after the addition of GMt. GMt induced the enrichment of the excellent functional bacteria of the phylum Proteobacteria as well as the genus Massilia and Sphingomonas. The main immobilization mechanisms of heavy metal(loid)s by GMt include electrostatic interaction, complexation, precipitation and oxidation. The addition of the GMt also optimizes the soil bacterial community structure, which further facilitates the immobilization of heavy metal(loid)s. Our results confirm that the novel GMt has a promising application in the immobilization and stabilization of heavy metal(loid)s contaminated soils in non-ferrous metal smelting areas.

AB  - Flotation reagents, especially new chelating agents represented by α-nitroso-β-naphthol, are the main components of cobalt mining drainage. This study reports the degradation of α-nitroso-β-naphthol by simulated UVA-B (280–400 nm) activated systems using three common oxidants, hydrogen peroxide, sodium persulfate and potassium monopersulfate at a laboratory scale using a photoreactor. Parameters which can affect the degradation process were investigated and comparison of the degradation performance of the three systems were made. Based on the results, UVA-B/sodium persulfate system exhibited best performance towards the removal of α-nitroso-β-naphthol with a lower cost of oxidant and energy consumption compared to the others. The removal efficiency was found to increase as the oxidant dosage and the UVA-B power increases. Only potassium monopersulfate could be activated by bicarbonate and chloride ions, and SO4 2− has insignificant effect on the removal efficiency of α-nitroso-β-naphthol for all systems while NO3 − inhibited the degradation of α-nitroso-β-naphthol. In the UVA-B/hydrogen peroxide system, the hydroxyl radical had a leading role in the degradation of α-nitroso-β-naphthol, while in the other two systems, the degradation of α-nitroso-β-naphthol was mainly caused by the hydroxyl and sulphate radicals. Ten major intermediates from α-nitroso-β-naphthol degradation in the three oxidation systems were identified by gas chromatography and mass spectrometry. In summary, this report could be a great input in developing UVA-B activated oxidants-based treatment technologies. The UVA-B/sodium persulfate system is strongly recommended for its consideration in the treatment of mine impacted wastewaters. UVA-B/SPS is the most efficient, economical and energy-saving technique for the degradation of αNβN compared to UVA-B/HP and UVA-B/PMS systems.

abstract = "Flotation reagents, especially new chelating agents represented by α-nitroso-β-naphthol, are the main components of cobalt mining drainage. This study reports the degradation of α-nitroso-β-naphthol by simulated UVA-B (280–400 nm) activated systems using three common oxidants, hydrogen peroxide, sodium persulfate and potassium monopersulfate at a laboratory scale using a photoreactor. Parameters which can affect the degradation process were investigated and comparison of the degradation performance of the three systems were made. Based on the results, UVA-B/sodium persulfate system exhibited best performance towards the removal of α-nitroso-β-naphthol with a lower cost of oxidant and energy consumption compared to the others. The removal efficiency was found to increase as the oxidant dosage and the UVA-B power increases. Only potassium monopersulfate could be activated by bicarbonate and chloride ions, and SO4 2− has insignificant effect on the removal efficiency of α-nitroso-β-naphthol for all systems while NO3 − inhibited the degradation of α-nitroso-β-naphthol. In the UVA-B/hydrogen peroxide system, the hydroxyl radical had a leading role in the degradation of α-nitroso-β-naphthol, while in the other two systems, the degradation of α-nitroso-β-naphthol was mainly caused by the hydroxyl and sulphate radicals. Ten major intermediates from α-nitroso-β-naphthol degradation in the three oxidation systems were identified by gas chromatography and mass spectrometry. In summary, this report could be a great input in developing UVA-B activated oxidants-based treatment technologies. The UVA-B/sodium persulfate system is strongly recommended for its consideration in the treatment of mine impacted wastewaters. UVA-B/SPS is the most efficient, economical and energy-saving technique for the degradation of αNβN compared to UVA-B/HP and UVA-B/PMS systems.",

AB  - The combined effects of antimony (Sb) and sodium diethyldithiocarbamate (DDTC), a common organic flotation reagent, on soil microbial activity and speciation changes of heavy metals were investigated for the first time. The results showed that the exchangeable fraction of Sb was transformed to a stable residual fraction during the incubation period, and the addition of DDTC promoted the transformation compared with single Sb pollution, probably because DDTC can react with heavy metals to form a complex. In addition, the presence of DDTC and Sb inhibited the soil microbial activity to varying degrees. The growth rate constant k of different interaction systems was in the following order on the 28th day: control group >= single DDTC pollution > combined pollution > single Sb pollution. A correlation analysis showed that the concentration of exchangeable Sb was the primary factor that affected the toxic reaction under combined pollution conditions, and it significantly affected the characteristics of the soil microorganisms. All the observations provide useful information for a better understanding of the toxic effects and potential risks of combined Sb and DDTC pollution in antimony mining areas.
