Continuous hydride generation, using sodium tetrahydroborate(III) as a reductant in conjunction with atomic absorption spectrometry (AAS) and inductively coupled plasma emission (ICP-AES), has been used to form arsines selectively from arsenate (AsV), arsenite (AsIII), monomethylarsonic acid (MMAA) dimethylarsinic (DMAA). The reaction media studied have shown allow the rapid determination of AsIII alone, DMAA AsIII+ AsV "total" arsenic, i.e., AsV+ MMAA + DMAA. Interference effects produced...
Concentrations in Gulf of Mexico slope sediment material soluble methanol and benzene as high 4.5 percent are shown to be attributable biodegraded petroleum. Associated carbonate deposits organic sulfur the products microbial oxidation petroleum sulfate reduction. The results chemical carbon isotope analyses indicate that concentrations hydrocarbon gases, from methane pentane, rather than microbiologically derived. These hydrocarbons, believed have been produced thermally at depth, probably...
Preliminary research has been concerned with the selective determination of arsenate (AsV), arsenite (AsIII), monomethylarsonic acid (MMAA) and dimethylarsinic (DMAA) using continuous hydride generation atomic absorption spectrometric detection. These studies (Part I) highlighted certain media as being suitable for monitoring AsIII, AsIII+ AsV, DMAA alone AsV+ MMAA + DMAA. Details are provided application these procedures to arsenic species in contaminated streams draining mineralised areas...
Both sulfuric and carbonic acid improved sulfide removal by lowering pH, but only preserved alkalinity proved less corrosive. To determine water quality effects on groundwater treatment for hydrogen sulfide, the authors compared (H 2 SO 4 ) pH adjustment pretreatment in a pilot‐scale (40‐gpm [2.5‐L/s]) randomly oriented packed tower. Pretreatment with either H or carbon dioxide (CO to 6.0 resulted > 95 percent tower feedwater concentrations of 2.5 mg/L. However, utilization loss finished...
This paper presents results from tests in a flame tube facility, where bio-derived alternate fuel was compared with JP-8 for emissions and general combustion performance.A research version of General Electric Aviation (GE) TAPS injector used the tests.Results include efficiency gaseous emission measurements, 2D planar laser-based imaging as well basic flow visualization flame.Four inlet test conditions were selected that simulate various engine power relevant to NASA Fundamental Aeronautics...
This paper presents results in which we compare fuel staging and its effect on spray pattern, velocity speciation during combustion for several inlet conditions using a GE TAPS injector configuration. Planar laser-induced fluorescence (PLIF), particle image velocimetry (PIV) phase Doppler interferometry (PDI) were used to investigate patterns velocity. The 2D PIV provides slices the flow of axial-vertical or axial horizontal components. With 3D PDI, obtained 3 components velocity, drop...
According to Elena Garro, "the great writer will be the one who presents Mexican as a universal being." In her novel Recollections of Things Come she achieves this goal primarily through an incessant infusion mythic and archetypal motifs, elements that constitute cornerstone study.
