底泥中汞的流动注射-氢化物原子吸收光谱法检测

Determination of Mercury in River Mud by Flow Injection-Hydride Atomic Absorption Spectrometry

流动注射分析系统与氢化物发生原子吸收光谱仪联用 ,测定底泥中的汞 ,操作简便 ,稳定性较好 ,而且样品和试剂消耗量较少 ,可用来进行痕量样品的测定。方法的线性范围为1～20μg/L,检出限为0.005mg/kg。

The content of mercury in river mud was determined by flow injection-hydride atomic absorption spectrometry. The method is characterized by simplicity and stability of operation, and less amounts of sample and agents. The method is suitable to determine trace sample with a linear range of 1～20 μg/L and detection limit of 0.005×10-6.
