目的建立一种简便有效的血中汞含量的测定方法。方法血样经高压消解罐消化后,用原子荧光分光光度法测定汞含量。结果在适宜的条件下,方法相对标准偏差为2.9%~6.2%,回收率为96.6%~103.3%,最低检出限为0.052μg/L。结论方法操作简便,所使用的设备价格低廉,灵敏度高,重现性好,可满足职业人群血汞的检测需要。 Objective To establish a simple and effective method for the determination of mercury in blood. Methods After the blood samples were digested in a high-pressure digestion tank, mercury content was determined by atomic fluorescence spectrophotometry. Results Under appropriate conditions, the relative standard deviations (RSDs) of the method were 2.9% -6.2% and the recoveries were 96.6% -103.3%. The minimum detectable limit was 0.052μg / L. Conclusion The method is easy to operate, the equipment used is cheap, sensitive and reproducible, which can meet the detection needs of blood mercury in occupational population.
