  • Electrokinetic delivery of permanganate into low-permeability soils

    A bench-scale study was conducted to investigate the feasibility of using electrokinetics as a method of delivering an oxidant into kaolin, a low-permeability soil. Potassium permanganate (KMnO4) was chosen as the oxidant, and in separate tests, KMnO4 was introduced at the anode, the cathode and both electrodes to investigate (1) the extent of oxidant transport via ...

  • Operating a two-stage microbial fuel cell–constructed wetland for fuller wastewater treatment and more efficient electricity generation

    By integrating microbial fuel cells (MFCs) into constructed wetlands (CWs) the need and cost of building a reactor are eliminated, while CWs provide the simultaneous redox conditions required for optimum MFC performance. Two single-stage MFC-CWs, with dewatered alum sludge cake as the main wetland medium for enhanced phosphorus removal, were operated to determine the effects of electrode ...

  • pH/ORP Sensors for Metallurgical Applications

    Importance of pH Measurement Hydrometallurgical concentrating and refining applications require pH/ORP sensors to withstand aggressive environments while maintaining accurate measurement. Processes such as cyanide leaching (e.g gold) and solvent extraction (e.g. copper, nickel, zinc) require pH and ORP to be at very specific values to yield the desired chemical species. pH may need ...

  • Iron Oxyhydroxide reduction in simulated wetland soils: Effects of mineralogical composition of Iris paints

    Reducing conditions in soils can be documented by the voltage measured between Pt and reference electrodes (Eh) or by using dyes like ,-dipyridyl for identifying reduced species (such as Fe2+). Indicator of Reduction in Soils (IRIS) tubes have been recently introduced as an alternative approach for documenting reducing conditions in soils, where a synthetic Fe oxyhydroxide painted on polyvinyl ...
