英文摘要 | A newly developed method for the determination of bromine (Br) and iodine (I) in low- to high-salinity aqueous samples by ICP-MS was established. Matrix related isobaric interferences (40Ar39K and 40Ar38Ar1H on 79Br) have been quantitatively estimated in the kinetic energy discrimination (KED) operation mode and the standard (STD) mode; it was shown that such interferences can be efficiently eliminated using the KED mode with He as a collision reaction gas. In addition, samples with high salt concentrations were analysed after pre-treatment using H-form cation-exchange resin with low dilution factors (10 or 20), rather than the high dilution factors (>200) reported in previous studies. The values for the total procedure blank of Br and I from this process were 0.784 and 0.015 μg L-1 , respectively. The Br and I limits of detection (LOD) and spiked recoveries for this ICP-MS method were 0.1104 and 0.0013 μg L-1 and 98.9–100.9 % and 98.0–102.9 %, respectively. The present method was successfully applied for the rapid and direct determination of Br and I in seawater and other aqueous samples. |
