| 摘 要： | 在过氧化氢溶液及硝酸镍存在下，用石墨炉原子吸收法测定化妆品中砷的含量，砷的浓度在0-1mg/L时与吸光度线相关，线性方程为A=0.838c 0.003，相关系数为0.99994。对液体和固体化妆品中的砷进行测定，砷的加标回收率为98.3%-98.7%，测定结果的相对标准偏差为0.65%-1.50%。

| Abstract: | Arsenic in cosmetics was determined by graphite furnace atomic absorption spectrometry with the presence of Ni-NO3 and hydrogen peroxide solution. The concentration of As is a linear correlation with the absobance in the range of 0~1 mg/L. The linear equation is A = 0. 838c 0. 003 with the correlative coefficient of 0.99994. By the determination of solid and liquid samples, the recoveries of As are 98.3% ~98. 7% , and RSD are 0.65%~1.50% . |
