Original Paper


Here we demonstrate that precipitation of dissolved inorganic carbon (DIC) to at pH 10.26, 11.38 and 12.11 does not cause measurable carbon isotope fractionation. However, NaOH solution prepared under standard laboratory procedure and used to increase pH value for precipitation of BaCO3 can be contaminated by atmospheric CO2. In our experiment, δ13C value in the contaminant DIC was −24.30‰, which resulted in decrease in the δ13C(DIC) value by 0.03, 0.07 and 0.22 at pH 10.26, 11.38 and 12.11, respectively.
