Abstract
    Pretreatments were used to remove organic “contaminant” material prior to isotopic analyses of coral skeletal samples. We conducted one experiments to test the pretreatment effect of 30% hydrogen peroxide (H2O2) on the boron isotopic composition of inorganic carbonate. The experimental results indicate that H2O2 can change the boron isotopic composition.
