CARBON-13 ISOTOPE EFFECTS IN SYSTEMS CONTAINING CARBON DIOXIDE, BICARBONATE, CARBONATE, AND METAL IONS
The fractionation of 13 C between CO 2 (g) and CO 3 − --HCO 3 − (aq) in solution has been studied in single stage experiments using carbonic anhydrase to catalyze the hydration of CO 2 . Added metal ions, pH of the equilibrium mixture, and temperature are found to play important roles in the overall...
