摘要
模拟人体皮肤环境,采用酸性汗液处理样品,通过氢化物发生-原子荧光光谱法测定仿真饰品中可萃取砷、锑、汞和硒。优化了实验条件,研究了共存离子的干扰。砷、锑、汞和硒的检出限分别为0.044、0.011、0.003、0.041μg/L。采用该法对仿真饰品进行测定,测定结果的相对标准偏差为2.9%～9.1%(n=3),回收率为88.2%～108.5%。
Sample of imitation jewelry was treated with artificial acid sweat solution which was simulated human＇ s skin condition, and a method for determination the extractable As, Sb, Hg and Se by hydride generation - atomic fluorescence spectrometry （ HG - AFS） was established. Test conditions was optimized and the interference of coexistence ions were studied. The detection limits were 0. 044, 0. 011, 0. 003, 0. 041 p,g/L for As, Sb, Hg and Se respectively. The imitation jewelry was determined, the RSD was 2.9% - 9.1% （n =3） , and the recoveries of the four elements ranged from 88.2% to 108.5%.
