N2 - Bromine naturally occurs mainly in the form of bromide and is usually
considered as a conservative tracer in the groundwater system. However,
nowadays many synthetically produced organobromine compounds are
introduced into the environment by humans. Due to a possible toxic
effect of these compounds, investigation of their fate in the nature is
of the utmost importance. In this sense, examination of isotopic
composition of inorganic and organic bromine may serve as a powerful
tool for understanding Br geochemical cycle. Due to a relatively small
mass difference between the isotopes 81Br and 79Br, bromine isotope
fractionation originating from biotic and abiotic processes is expected
to be in the range of several permille. Therefore, a highly precise
technique for the bromine isotope ratio analysis is required. This work
presents a new methodology for the precise determination of bromine
isotope ratio in inorganic bromides and individual organic compounds by
MC-ICPMS. Attained external precision (2σ) up to 0.1‰
allowed employment of the developed technique for determination of the
bromine isotope composition in organic and inorganic bromides and Br KIE
in biogeochemical processes.
