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  - The heavy metal and organic pollution caused by mining activities keep attracting attention, thus an economic and efficient treatment for combined pollution is pressing. In this study, the simultaneous removal performance of typical organic flotation reagent 8-hydroxyquinoline (8-HQ) and Cr(VI) was investigated via heterogeneous Fenton process induced by a novel polydopamine (PDA) functionalized attapulgite supported nano sized zero-valent iron (nZVI) composite (PDA/ATP-nZVI). Batch experiments showed that PDA/ATP-nZVI had better catalytic reactivity and reduction ability than both ATP-nZVI and nZVI. Under acidic condition, 96.0% of 8-HQ was degraded accompanied with the 42.5% of total organic carbon (TOC) decrease, while 95.8% of Cr(VI) removal efficiency was accomplished by PDA/ATP-nZVI. PDA not only served as redox mediator in expediting electron transfer, but also acted as electron donor that accelerated transformation from Fe(III) to both dissolved Fe(II) and surface Fe(II), which resulted in the increased degradation of 8-HQ. The synergic removal behavior between 8-HQ and Cr(VI) was discussed and the reaction mechanism in the persulfate (PS)-PDA/ATP-nZVI system was also explored. This study developed a highly efficient heterogeneous catalyst, and demonstrated that the PS-PDA/ATP-nZVI system had a potential for remediation of mine environment polluted by both heavy metals and organic flotation reagents.
