Abstract

Utilizing the 352.45 nm absorption line of nickel , 0.05%～1.3% content of nickel being determined in nickel ore by using flame atomic absorption method. The linearity range of nickel is 20～1000 μg/50 mL, recovery range is 98.1%～103.8%, RSD(n=10)is 2.03%.This flame atomic absorption analysis method can expand the linearity range of nickel and no near spectra interference.
