Atomic Absorption Spectrometry to Measure the Content of Titanium in the Stainless Steel

The nitrous oxide-ethane flame atomic absorbing spectral method to measure the content of Titanium in stainless steel is studied.This paper introduces the optimum measuring conditions for Titanium and the potency in which a fine liner range, and makes also a synthetic consideration to interference factors. The method has the advantages of high sensitivity, less interference and good in selectivity and reappearance. The relative standard deviations are all less than 1.0%(n=6)in six sample measuring, and the standard adding recovery is in the range of 97.0%～100.0%(n=6). The practice shows that the method is fully suitable to measuring the content of Titanium in the stainless steel.
