摘要
本文用流动注射冷原子吸收光谱法测定了痕量汞,采样频率为140个样次/小时的速度,检出限为0.15ug/L(3δ),对于10ug/L水平汞标准液相对标准偏差为2.9%(n=11)
The flow-injecting atomic absorption spectrophotometry is used to betermine the trace Hg in food. The sampling frequency is chosen to 140 times /h. the detecting minimun, 0. 15 μg /L. the standard deriation . 2. 9 % (n =11).
