| 摘 要： | 利用石墨炉子吸收光谱法测定蒸汽发生器循环水和蒸汽冷凝水中的铯则间接测定蒸汽含水率。蒸汽含水率等于冷凝水中铯的浓度除以循环水中铯的浓度。石墨炉原子吸收光谱可以准确测定０．１ｇ／Ｌ至１ｍｇ／Ｌ浓度的铯，样品中可能存在的一些物质对测定没有干扰。本方法可以满足测定蒸汽含水率的要求，实现了数百份含水率样品的测试。

| Abstract: | The steam moisture was determined indirectly by determination of caesium concentrations in the recirculated water and feedwater in steam generator by the graphite furnace atomic absorption spectrometry. The moisture carryouer was defined by the ratio of caesium concentration in feedwater to caesium concentration in recirculated water. The caesium concentration from 0.1 mg/L to 1 mg/L could be determined accurately by graphite furnace atomic absorption spectrometry. The influence from foreign ions which may appear in recirculated water and feedwater was not found. The method could satisfy the need of moisture carryover measurement. Hundreds of samples of moisture carryover have been determined. |
