微波消解冷原子荧光法测定市售猪肉中的痕量汞
Determination of Trace Mercury in Pork by Microwave Digestion-Hydride Generation-Atomic Fluorescence Spectrometry
【摘要】 采用微波消解,冷原子荧光法测定了猪肉中的痕量汞。汞的回收率在90.7%~98.8%之间;相对标准偏差(RSD)2.62%;检出限为0.010μg/mL;线性范围0~12μg/mL。
【Abstract】 Trace mercury in pork was determined by microwave digestion-hydride generation-atomic fluorescence spectrometry (HG-AFS). The microwave digestion of samples was used, and the optimum conditions for the digestion were developed. The results showed that the detection limit was 0.010 ng/mL, the relative standard deviation (RSD) was 2.62%, and the recovery of mercury in pork samples was 90.7%~98.8%.
