    摘要： The concentration of a C.sub.1 to C.sub.4 alcohol in an essentially water immiscible organic system is accurately determined by a simple and quick process. A sample of the water immiscible organic system containing less than about 0.01% (W/V) of the alcohol is contacted with an aqueous layer of alcohol oxidase immobilized on an electrode for measuring dissolved oxygen content. Ethanol in the water immiscible organic system partitions into the aqueous layer where alcohol oxidase catalyzes oxidation of the alcohol. Oxygen consumed during the oxidation is measured by the electrode, and the concentration of alcohol determined therefrom. To obtain less than about 0.01% alcohol in the sample, the sample may be diluted with the water immiscible organic system.

    摘要： An electric plasma arc apparatus and method produces nitrogen compounds, solely using ambient air extracted in proximity to the apparatus. The nitrogen compounds are brought into contact with a water processing system, forming nitrate on-site. Hydrogen sulfide present in the water processing system is removed, and the production of hydrogen sulfide by sulfate-reducing bacteria (SRB) is eliminated by introducing nitrate into the system, whereby denitrifying microorganisms, using the nitrate, outcompete the sulfate-reducing bacteria for the available carbon nutrients, thus preventing the SRB from producing hydrogen sulfide. Nitrate ions generated in the water processing system which contains the denitrifying microorganisms can enhance oil recovery by means of microbial enhanced oil recovery mechanisms. Further, the electric plasma arc apparatus and methodology eliminate major costs of conventional treatment techniques, including the transportation and storage of nitrate and the need for a continuous supply of natural gas and water.

    摘要： A system for removing cyanide and related species from a cyanide-containing waste fluid, for example, of the sort generated by mining operations, includes means for generating hydrogen peroxide by the burning of a fuel and the quenching of that burning with the waste fluid. At least a portion of the cyanide content of the waste fluid is eliminated by oxidation with the hydrogen peroxide, and the quenching can also provide organic material to serve as a carbon source for microbes which degrade residual cyanide in the treated waste stream.
