摘要
本文研究了无火焰非色散原子荧光法测定头发、尿及指甲中微量汞的方法。方法简便快速、灵敏。在选定的条件下,方法检出限为:头发0.0025μg/g Hg,尿0.0023μg/ml Hg,指甲0.0020μgHg/g。工作曲线线性范围0.001～0.100μg/2ml Hg。相对标准偏差(n=16)小于4％;标准回收率95％～106％。36种共存元素其含量低于允许存在量,不干扰汞的测定。
A simple, rapid and sensitive method for the determination of trace mercury in hair, urine and nail by flameless non-dispersive atomic fluorescence spectrometry has been studied. Under the optimum conditions, the detection limits of mercury were as follow:0.0025μg/g in hair,0.0023μg/ml in urine and 0.0020μg/g in nail. The calibration curves are linear in the range of 0.001 to 0.1001μg/2ml for Hg. The relative standard deviation of 16 determinations was less than 4％, and the recovery was 95.4％～106.7％, 36 elements do not interfere with the determination of Hg.
