The redox transformations, phase transformation, and mobility of selenium species play an important role in the environment in terms of the transport and bioavailability of selenium oxyanions, selenium contamination in waters, and toxicity to organisms. Several selenium removal techniques have been developed to decrease the selenium concentration in water such as ion exchange, reduction, precipitation, and bioremediation, among others. Stable isotope approach has been used and reported in the literature to study kinetic isotope effects (KIE) of selenate reduction in abiotic and biotic environment.
