Passive treatment based on iron biological oxidation is a promising strategy for As-rich acid mine drainage (AMD) remediation. In the present study, we characterized (by 16S rRNA metabarcoding) bacterial diversity in field-pilot bioreactor treating extremely AMD situ, over six months monitoring period. Inside bioreactor, communities responsible and arsenic removal formed biofilm ("biogenic precipitate") whose composition varied time space. These evolved throughout from structure at first...
Industrial chlorinated solvents continue to be among the most significant issues in groundwater (GW) pollution worldwide. This study assesses effectiveness of eight novel oxidation treatments, including persulfate (PS), ferrous sulfate, sulfidated nano-zero valent iron (S-nZVI), and potassium ferrate, along with their combinations, for potential situ remediation GW polluted (1,2-dichloroethylene, trichloroethylene, tetrachloroethylene). Our bench-scale results reveal that combined addition...
As(<sc>iii</sc>)/As(<sc>v</sc>) ratio determined from orthophosphoric acid extraction/HPLC-ICP-MS matched XANES results, allowing routine measurement of As oxidation state in mine drainage precipitates.
The remediation of groundwater containing arsenic is a problem that has been addressed using adsorption processes with granulated materials in columns, but the itself could be improved by micro-sized adsorbents stirred systems. In this study, arsenate (As(V)) batch experiments were performed granular ferric hydroxide (GFH) and two derived materials. Reduced-size produced energetic ball milling, giving final sizes 0.1–2 µm (OF-M samples) ultra-sonication, producing 2–50 (OF-U samples)....
The employment of granular ferric iron-(oxy)hydroxides, a well-known economic and effective method, lowers arsenic concentrations in different water types. However, for direct application polluted groundwaters, there is need to develop new injectable adsorbents aquifers that could also neutralize acidic media. In this context, hydroxide-calcite (GFH-C) adsorbent was size-reduced 0.4–50 µm by sonication with the aim improving (i) adsorption As(III) As(V) at pHs (ii) pH control through...
Interaction between Portland cement, rock (siliceous limestone) and acid mine drainage (AMD) from the Iberian Pyrite Belt (IPB) was studied by means of column experiments at laboratory scale. Synthetic acidic solutions (pH = 2) containing sulfate, Fe(II), Al, Mg minor elements such as divalent cations (Cd, Zn, Cu, Ni Cd) an anion As(V) were injected. The interaction dominated dissolution calcite (main phase) portlandite (one main phases cement). Dissolution these increased pH up to ≈ 12...
