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.
采用电感耦合等离子体质谱法（ICP-MS）测定植物中的钯。详细研究了ICP-MS测定中钯的光谱干扰。基于丰度比，采用数学校正方程校正钯的光谱干扰。通过与二乙基二硫代氨基甲酸钠（DDTC）络合分离法及标准物质（GBW 07293）中铂族元素（PGEs）测定方法对比，评估了该方法的潜力。实验结果表明，采用本研究方法可对2005年在中国北京主干道沿线采集的国槐、一年生草本植物、冬青和丁香树叶片中的钯进行测定，结果令人满意。
