目的：建立了石墨炉原子吸收光谱法测定化妆品中铬含量的方法。方法样品经硝酸-过氧化氢微波消解后，采用标准曲线法测定。结果在浓度0n g/m l～20n g/m l范围内方法线性关系良好，相关系数r=0.9996，检出限为0.006μg。重复性测定结果的相对标准偏差为4.3%（n=6），加标回收率在101.8%～108.3%之间。结论本方法简单易操作，重复性及回收率较好，适用于化妆品中铬的测定。
目的：建立瞭石墨爐原子吸收光譜法測定化妝品中鉻含量的方法。方法樣品經硝痠-過氧化氫微波消解後，採用標準麯線法測定。結果在濃度0n g/m l～20n g/m l範圍內方法線性關繫良好，相關繫數r=0.9996，檢齣限為0.006μg。重複性測定結果的相對標準偏差為4.3%（n=6），加標迴收率在101.8%～108.3%之間。結論本方法簡單易操作，重複性及迴收率較好，適用于化妝品中鉻的測定。

Objective To establish an GFAAS method for the measurement of Cr in cosmetics. Methods Samples was digested by microwave with nitric acid and hydrogen peroxide,then determined with standard curve method. Results It exhibited a good line-arity in the range of 0ng/ml~20ng/ml with correlation coefficient(r) of 0.9996, and the detection limit was 0.006μg.The relative standard deviation of repetitive was 4.3% (n=6),the recovery of the method was from101.8% to 108.3%. Conclusion This method is simple,easy to operate,precise and reliable,Suitable for determination of chromium in cosmetics.
