| Abstract: | A method for determination of Chromium in Titanium by Inductively Coupled Plasma-Optical Emission Spectrometry （ICP-OES） was presented in this paper. The experiments studied dissolution methods, selection of analytical spectral lines of elements,acidity and interference conditions, and optimized instruments operating conditions.Under the optimum analytical conditions for a standard sample spiked recovery test, the recovery rate reached between 97% and 103%. For accuracy and precision test, the test results showed that the analysis resuhs were in conformity with certified values, and the relative standard deviation was less than 1.0%. |
