本文描述了用~(203)Pb的同位素稀释亚化学计量法测定土壤样品中微量铅的方法。对日本及中国土壤标准样品的测定表明,本方法的准确度、精密度均良好,而对铅的检测限为0.1μg。
This paper describes a method for the determination of trace lead in soil samples by ~ (203) Pb isotope dilution stoichiometry. The determination of standard soil samples in Japan and China showed that the method was accurate and accurate, and the detection limit of lead was 0.1μg.
