摘要：In this study, optimal conditions to analyze lead isotope ratios in soil using ICP-MS were examined. For the extraction of lead from soil, a microwave digestion system without other operations was the most useful to prevent contamination and error, because sufficient extraction was performed and measured values had a high degree of accuracy. In ICP-MS measurement, optimal conditions were achieved with a method in which lead concentration was diluted to about 0.10 mg/L and seven repetition measurements were performed with a dwell time of 0.5 seconds. However, it would be necessary to introduce equal amount of lead to the ion source by making sample concentrations equal and to correct measurement values with a standard value.
