以流动式连续进样方式,用还原气化-金丝富集-发射光谱法测定了天然水中痕量的总汞和无机汞。并用差减法求出有机汞。该方法的检出下限为1×10~(13)克汞,动态线性范围为5×10~(12)——1×10~(-7)克汞。
The trace mercury and total mercury in natural water were determined by flow-in-continuous injection with reduction gasification-gold enrichment-emission spectrometry. And use the subtraction method to find organic mercury. The detection limit of this method is 1 × 10 ~ (13) g mercury with a dynamic linear range of 5 × 10 ~ (12) -1 × 10 ~ (-7) g mercury.
