Abstract

The determination of nickel in copper-bonded diamond tools was tedious and needs to use large amount of reagents by using chemical analysis and visible spectrophotometry.In this paper,we can determine the content of nickel directly by flames atomic absorption spectrometry without separating the copper from the copper-based metal bond.In this way,its recovery rate can reach 98.9%-99.5% and the relative standard deviation was 1.96%-2.46%.It was reliable that the regression coefficient of working curve was 0.99834.
