四苯硼钠沉淀-原子发射光谱法测定卤水中的铷、铯

Precipitation of Sodium Tetraphylborate-Atomic Emission Spectrometric Determination of Rubidium and Cesium in Brine

根据卤水样品中钾的含量用四苯硼钠定量沉淀卤水中的钾、铷和铯,沉淀过滤灰化后加入定量的氯化钾,在标准系列中加入等量的氯化钾和硼酸,在相同基体条件下用原子吸收光谱法测定卤水样品中的铷和铯。

Potassium, rubidium and cesium in the sample brine were quantitatively precipitated with sodi- um tetraphylborate, and the precipitate were filtrated and incinerated, then the cineration were redissolved and the potassium chloride were added, the same amount of potassium chloride and boric acid were added to the standard series. The last, the rubidium and cesium of both the sample and standard series were de- tected with atomic emissions spectrometric in the same matrix.
