摘　　要：建立了用电感耦合等离子发射光谱(ICP-AES)法测定Pd/-γAl2O3-SiO2催化剂中微量钯含量的方法。确定了适宜的炬管高度、火焰水平位置、高频发生器正向功率及进样速度,考察了基体效应,在此条件下测定的数据具有较高的重复性和回收率。用该法对实际样品进行了分析,得到满意的结果。A new method of determining of micro - amount - palladium in Pd/γ-Al2O3-SiO2 catalysts by ICP- AES（Inductively coupled plasma- atomic emission spectrometry ） was studied. Some influence roles of experimental results were also investigated. The results showed that the RSD was lower than 1.0 % and the recovery was 90.7 % --110.2 % for this method that would be applied to determine the micro - amount - Palladium in Pd/γ-Al2O3-SiO2 catalysts with satisfactory results.
