Accelerated dissolution of iridium anode in the presence of organic compounds

Nature Communications
Iridium oxide is commonly used as a catalyst for the oxygen evolution reaction (OER) in various electrolysers. In this study we investigate the impact of organic compounds, such as ethanol, in the accelerated dissolution of iridium oxide, particularly in

Biotreatment of industrial tannery wastewater using Botryosphaeria rhodina [PDF]

Journal of the Serbian Chemical Society, 2011
The treatment of a tannery wastewater was performed on the laboratory scale using the ascomyceteous fungus Botryosphaeria rhodina MAMB-05, a ligninolytic and a constitutive producer of laccases (EC: 1.10.3.2). The wastewater samples were collected in the

Direct Determination of Oxygen in Organic Compounds

Croatica Chemica Acta, 1970
The method for direct oxygen analysis as described by Schutze, Zimmerman and Unterzaucher has been modified. The Korbl catalyst was employed to remove some interfering gases and to oxidize carbon monoxide to carbon dioxide. The described method has been successful for the determination of oxygen in compounds which, in addition to carbon, hydrogen and ...
