Determination of Mercury in Blood by Atomic Fluorescence Spectrometry with a Thiourea Extraction Method / 环境与健康杂志

ABSTRACT

Objective To develop a method for determination of mercury in blood by atomic fluorescence spectrometry. Methods Using a thiourea extraction method, the mercury in blood is determined by atomic fluorescence spectrometry. Results The linearity of calibration curve of mercury was in the concentration of 0.000-10.00 ?g/L. The detection limit was 0.06 ?g/L. The recovery rates were 95.5%-100.3%.The RSDs were 4.1%-4.5%. Conclusion The method has the advantages of simple operation, high sensitivity, good repeatability and is applicable to the determination of mercury in blood.
