以硫氰酸钾作金、铂、钨的掩蔽剂，用ＳｎＣｌ２在强碱介质中还原化合汞为原子汞进行汞的冷原子吸收测定，本法灵敏度为 ０．００５ｍｇ／５ｍｌ。 通常情况下，汞的冷原子吸收法是在适宜的酸度下用ＳｎＣｌ２等还原剂还原化合汞为汞蒸气进行原子吸收测定。但在某些行业（如电
With potassium thiocyanate as a gold, platinum and tungsten masking agent, SnCl 2 was used in reducing mercury in atomic absorption spectrometry for the determination of mercury by atomic absorption spectrometry. The sensitivity of this method was 0.005 mg / 5 ml. Under normal circumstances, mercury cold atomic absorption method is the appropriate acidity with SnCl2 and other reducing agents to reduce the combined mercury as mercury vapor atomic absorption determination. But in some industries (such as electricity
