The sulfate/nitric acid extracts of zinc, nickel and copper from the catalyst waste were determined by flame atomic-absorption spectrophotometry, in which the recovery of standard addition and relative standard deviation were in the range of 93.2% to 108.5% and 0.4% to 1.7%, respectively. The results indicated that it was an available method for the analysis of extracts from catalyst waste.
