Bromine
is used in many areas such as agricultural chemicals, dyestuffs, insecticides,
pharmaceuticals and chemical intermediates. Some uses are being phased out for
environmental reasons, but new uses continue to be found. In this work, the
effects caused by different chemical environments in several bromine compounds
were studied using EDXRF spectrometry. The samples were excited by 59,5 keV
gamma rays emitted from Am-241 radioisotope source and characteristic K X-rays emitted from the samples were
counted by Si(Li) detector. Modifications
in values of energy of X-Ray line, full width at half maximum (FWHM), asymmetry
index (AI) were determined. In conclusion, the results of the present paper
demonstrate that the Bromine Kα and Kβ emission energies depend on the Br
chemical state and, therefore, their determination allows the chemical state
speciation of Br in a given sample.
