Bromine Determination

Abstract Organic compounds containing bromine, including methyl bromide, ethylene dibromide, and l,2-dibromo-3-chloropropane, have been used extensively for the fumigation of foods, or soils in which foods grow, making it necessary to determine residues of bromine and bromine-containing organic compounds. A large number of methods for the determination of bromine in foods, as organic, inorganic, and combined total bromide, have been developed. In methods for organic bromide, the bromine is converted to the inorganic form for measurement by titration, photometry, or other means. In recent years, instrumental methods have been developed in which the total bromine in the sample is determined, regardless of the state in which it exists. X-ray fluorescence and neutron activation analysis are the 2 instrumental methods used most widely. Residue data are presented for some typical bromine-containing samples.

Non Destructive

The article presents a methodical survey of standard non-destructive analytical methods applied recently to metal objects in the museum. These methods have helped to classify and describe particular pieces in the museum’s collection of metal objects in a more complex ethnological, historical and museological context.

Water Quality And Quantity

The Hydrology Ecology And Disturbance (HEAD-1 and HEAD-2) research programs in the Western Boreal Plains of North-Central Alberta, has provided objective delineation and determination of landscape units characterized by geology and climate. From these landscape indices can be developed that provide information on the scale at which forest, wetland, and aquatic systems are linked to their surroundings and the potential response of an area to particular disturbances. In collaboration with industry, government and NGO planners and ecologists this work establishes a hydrologic risk planning process that evaluates the ecological risk and monetary costs of forest harvest on forest succession and water quality and quantity.

Instrumental Methods

Iron analyses performed on used gas turbine lubricating oil samples by several variations of rotating disk–spark emission spectrography, atomic absorptiometry, and x-ray fluorescence spectrometry are compared with a quantitative wet chemical technique. The results indicate that emission spectrography with a cobalt internal standard, atomic absorptiometry with a nitrous oxide–acetylene flame, and x-ray fluorescence, both dispersive and nondispersive, are the most reliable instrumental methods. The iron contained in the samples exists primarily as particulates 1 µ or less in diameter.
