摘　　要：目的建立生物标本中微量锑的原子荧光测定方法。方法采取微波消解,氢化物发生-原子荧光光谱对生物标本中锑进行测定。结果全血和尿液标本在0~20μg/L线性范围内,其相关系数为0.999 1和0.999 7;头发标本在0~60μg/L线性范围,相关系数为0.999 4。全血、尿液、头发检出限分别为0.055、0.091、0.097μg/L,加标回收率97.5%~104.9%之间,相对标准偏差0.4%~2.8%。结论本方法线性范围宽,检出限低,操作简便,可用于生物标本中痕量锑的测定。Objective To establish a determination method with atomic fluorescence spectrometer to trace antimony in bio- material. Methods Using microwave digestion and hydride atomic fluorescence spectrometer , the content of antimony in biomaterial was determined. Results In linear range, coefficient of associations among several experiments were between 0. 999 1-0. 999 7. The detection limits of whole blood, urine and hair were 0. 055μg/L, 0. 091μg/L and 0. 097 μg/L. Recovery of standard addition was between 97.5%-104. 9% and RSD was 0.4%-2.8%. Conclusion The method has an advantage of low detection limit, high sensitivity and accuracy, simple and convenient, wide linearity. It can meet the re- quirements of trace antimony detection in biomaterial.
