Determination Method of High Content of Nickel in Ferronickel and Various Alloys Using Atomic Absorption Spectrometry

The atomic absorption spectrometric method was applied to the determination of the highconcentration of Nickel in ferronickel and other ferroalloys containing nickel. The influences ofexperimental parameters, such as wavelength, slit width, burner height,and fuel flow rate were evaluated.Instrumental conditions such as burner height, wavelength, fuel flow rate,and slit width have been optimized in a manner to achieve minimum absorption signal with low background. The effects of severalphysicalconditionslike slit width, fuel gas flow rate, burner height and calibration on the change in the absorbance of nickel under the optimized conditions were also studied. Theaccuracy of the procedure was sufficient and evaluated in comparison with other established methods suchas WDXRF and classical procedure by gravimetric method - Dimethylglyoxime (DMG). The applied procedure could be successfully applied for the determination ofnickel in ferronickel and other ferroalloys.
