我校化学系以冷原子吸收光谱测定汞的技术为基础,采用荧光转换技术,使被测量的253.7纳米紫外光,通过特定的荧光物质转变成可见光进行含汞量测定. 冷原子吸收光谱法,一般用原子吸收分光光度计的专用附件或测汞仪来测定汞.它们的分光系统均采用石英棱镜、光栅或紫外滤光片,以获得汞的共振线253.7纳米的单色
Based on the technology of cold atomic absorption spectrometry for the determination of mercury, the chemistry department of our university uses the fluorescence conversion technology to make the measured 253.7 nm ultraviolet light change into visible light through a specific fluorescent substance to measure the mercury content.Colon-atomic absorption spectrometry, Mercury is typically measured with a dedicated accessory to an atomic absorption spectrophotometer or a mercury detector, and their spectroscopic systems employ quartz prisms, gratings or UV filters to obtain a single line of 253.7 nm mercury resonance line
