Abstract
The method of determining nickel content in catalyst by air-acetylene flame atomic 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 %.
