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时与吸光度线性相关,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％。
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% .
