抄録

Isotope dilution-inductively coupled plasma mass spectrometry (ID-ICP-MS) was applied to the determination of lead in natural water, and its precision was compared to that of the conventional calibration method. Trace amount of lead in natural water was preconcentrated using a chelating resin of Chelex 100 before ID-ICP-MS, where the preconcentration factor of 50 was obtained. The concentrations of lead were 26.1pg/g and 266pg/g for the certified river reference materials (JAC 0031) and the pond water sample, respectively, with the RSD less than 1%.
