Abstract
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 ch elating resin of Chelex 100 before ID-ICP-MS, where the preconcentrati on factor of 50 was obtained. The concentrations of lead were 26.1 pg/ g and 266 pg/g for the certified river reference materials (JAC 0031) and the pond water sample, respectively, with the RSD less than 1%.
