本工作研究建立了封闭式火焰原子吸收法测定高放废液中钠、铁元素的方法。高放废液中含有少量的钚、镎和大量的裂变产物,用火焰原子吸收法在测量过程中产生气溶胶。为此,设计了专用手套箱,并与原子吸收仪结合在一起,形成一套完整的专用设备,较好地解决了对放射性气溶胶的屏蔽。 This work established a closed flame atomic absorption method for the determination of sodium and iron in high-level liquid waste. High-level liquid waste contains a small amount of plutonium, gallium and a large number of fission products, flame atomic absorption spectrometry in the measurement process to produce aerosols. To this end, the design of a special glove box and atomic absorption spectrometer together to form a complete set of special equipment, a better solution to the radioactive aerosol shielding.
