Abstract

[Objective] To develop a method for determination of titanium in skin-care products by graphite furnace atomic absorption spectrometry (GFAAS). [Methods] The sample was treated with wet digestion method,and the titanium in sample solution was measured by graphite furnace atomic absorption spectrometry (GFAAS). [Results] Graphite furnace ashing temperature was 900℃,and atomization temperature was 2 700℃; The coexistence of elements had no significant interference on the determination. Ti contents in samples were at the range of 0.10-0.15g / 100g,the relative standard deviations (RSDs) of the method were at the range of 0.50%-0.77%,and the recoveries were at the range of 94.0%-103.0%. [Conclusion] The method is easy to operate,high sensitive with good accuracy.
