摘要
研究了火焰原子吸收法测定催化剂中的镍的方法。在压力溶弹内用王水作溶剂消解试样，具有试剂用量少、不受污染等优点，该方法相对标准偏差小于2．0％（n=8），回收率在97．3％-102％。
The method of detenuining nickel content in catalyst by air- acetylene flame atomie absorption spectrometry was studied. The samples were digested in pressure digestion, and the solvent was aquaregia, it had advantages that the amount of reagent was a little and pollution was little, The RSD of the method were less than 2.0 % （ n = 8） ,and the recoveries were between 97.3 % ～ 102 %.
