摘要
提出了用火焰原子吸收光谱法测定加氢催化剂中钯的方法。研究了载体和混酸对钯的测定的影响 ,采用基体匹配法以消除干扰。该方法回收率在 95 .1%～ 10 2 .0 %之间 ,相对标准偏差在 1.2 5 %～ 2 .5 5
The method of determining palladium in adding hydrogen catalyst by flame atomic absorption spectrometry was proposed. The effect of carrier and mixture acid on palladium were researched. The interferences were eliminated by adding matched matrix. The recoveries of the method are between 95.1%～102.0% and the relative standard deviation are between 1.25%～2.55%.
