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%。 Simulated human skin environment, the samples were treated with acid sweat, and the extractable arsenic, antimony, mercury and selenium were determined by hydride generation-atomic fluorescence spectrometry. The experimental conditions were optimized and the interference of coexisting ions was studied. The detection limits of arsenic, antimony, mercury and selenium were 0.044,0.011,0.003,0.041μg / L respectively. The relative standard deviations (RSDs) were 2.9% ~ 9.1% (n = 3). The recoveries ranged from 88.2% to 108.5%.
