用 AFS- 2 30原子荧光光度计测定了生物样品中的铋 ,在最佳试验条件下 ,本法的最低检出浓度为 0 .5ng/g,线性范围 0～ 1 0 0 mg/ml,样品加标回收率 95.9%～ 1 0 0 .5% ,样品测定相对标准偏差为 5.5% The AFS-2 30 atomic fluorescence spectrophotometer was used to determine the bismuth in biological samples. Under the optimal experimental conditions, the minimum detectable concentration of this method was 0.5 ng / g and the linear range was 0 ~ 100 mg / ml. The sample The spiked recoveries ranged from 95.9% to 100.5%. The relative standard deviations (RSDs) were 5.5%
