Abstract：Inductively coupled plasma-mass spectrometry (ICP-MS) was employed to determine palladium in plants. The spectroscopic interferences with Pd in the ICP-MS determination were studied in detail. Spectral interferences with Pd were corrected using mathematical correction equation based on abundance ratio. The potential of the method was evaluated by the comparison with the method using complex separation by DDTC and the determination of PGEs (platinum group elements) in standard reference materials (GBW 07293). The experimental results showed that using the studied method, Pd could be determined in the leaves of Japanese pagoda, annual grass, holly and tine tree collected along main roads in Beijing (China) during 2005 with satisfactory.
