Abstract
Objective To establish an analytical method to determine arsenic in cosmetics with graphite furnace atomic absorption spectrometry. Methods Arsenic in cosmetics was determined by graphite furnace atomic absorption spectrometry with citric acid as a matrix modifier. Results The detection limit was 0.03 μ g/ g, the related coefficient of the standard curve for the present method was 0.997-0.999, and relative standard deviation was 4.7%, rate of recovery was 92%-106%. Conclusion Graphite furnace atomic absorption spectrometry is sensitive, reliable, simple and rapid for determination of arsenic in cosmetics.
