The effect of C02 on the speciation of bromine in low-temperature geological solutions: an XANES study
CO2-rich solutions are common in geological environments. An XANES (X-ray absorption near-edge structure) study of Br in CO2-bearing synthetic fluid inclusions has revealed that Br exhibits a strong pre-edge feature at temperatures from 298 to 423 K. Br in CO2-free solutions does not show such a feature. The feature becomes smaller and disappears as temperature increases, but reappears when temperature is reduced. The size of the feature increases with increasing X(CO2) in the fluid inclusion,...[Show more]
